In class 9th CBSE Maths syllabus, one of the topic is 'Polynomials'. It includes a definition of a polynomial in one variable, its coefficients, with examples and counterexamples, its terms, zero polynomial. The degree of a polynomial. Constant, linear, quadratic, cubic polynomials; monomials, binomials, trinomials. Factors and multiples. Zeros/roots of a polynomial/equation. State and motivate the Remainder Theorem with examples and analogy to integers. Statement and proof of the Factor Theorem. Factorization of ax2 + bx + c, a1 0 where a, b, c are real numbers, and of cubic polynomials using the Factor Theorem.Recall of algebraic expressions and identities. Further identities of the type (x + y + z)2 = x2 + y2 + z2 + 2xy + 2yz + 2zx, (x y)3 = x3 y3 3xy (x y) 3 + y3 + z3 - 3xyz = (x + y + z) (x2 + y2 + z2-xy - yz - zx) and their use in factorization of. polynomials. Simple expressions reducible to these polynomials.

thanku so much and learn the complete understanding of Polynomials class 9 CBSE and learn how to solve the questions in a very easy method

[@abhishektripathi1065]

Excellent way of teaching. Many thanks for the explanation.

[@apoorvasahare9213]

Sir second example mai Apne 5x diya tha par bad mai jab apne solve kiya tab apne 5x² liya . Ese to mera answer galat ajayega n...so please give right Q in starting itself

[@apoorvasahare9213]

In third Q also first you give us 8x and than you solve it by 8x² ,so how our answer get correct????

[@apoorvasahare9213]

In fourth Q also the answer is wrong . The correct will be 8

[@vilakshansharma9254]

Sir you are great.your teaching method is fantastic

[@proboy454]

Thank you for teching but one suggestion from my side is that you should write the answer at the same time instead of writing it before as it will be more easy to understand.

[@KulwinderKaur-ci5zu]

Please also make part 4

[@adityasingh4234]

Divide x+1by x+1 ka ans 1 hai

[@TruMath]

yes and learn the complete understanding of polynomials class 9 CBSE and learn how to solve the questions in a very easy method

[@saimatasneem5852]

Sir I am unable to understand that from where 4k/3-76/3 came ..

[@bhumisinghania9204]

Ya exactly . Me too . If anyone know this then plz tell us

[@amanjyotsingh1714]

sir cant we do anything with remainder ?

[@govindsinghbaghel6109]

Sir if we will multiply 64*6 then how we can get 128

[@DeepakSingh-td7jn]

It is divided

[@nawalgupta3004]

Sir I am not able to understand your 1st question

[@TruMath]

Please attend the class again

[@shaukatraza8292]

Very good

[@rashmigupta4211]

Sir in 6.29 why can't we put 7-a value in 1equation😐😐 one want to ask this question hit like 👇👇😊

[@gudduthakur5272]

At 6.14 b=7‐a why not a= 7‐b

[@vijaykumargupta5297]

Sir can you help in this question . Find the zeroes of the following quadrilatic polynomials and verify the relationship between the zeroes and the coefficients (¡) ×2 - 2× -8. (¡¡) 6×2 - 3 -7× , ( 6×2 - 7× - 3 ). Where this ( × ) sign means x not a multiple

[@anonymousx03]

Assume

[@ysrtrgamer9448]

Science lecture

[@vanshchaudhary3906]

On 4:18 in the question it was -8x but baadme wo -8x square likha hai sir ne

[@pujasharma9806]

Yes !! Aesa mistake tha yaa usko banana padega

[@Drawing_fun20]

Thank you sir and your teaching methods are very best******

[@مريم-ط5م6ي]

Yes thats correct

[@tapasiupadhyay5146]

Sir in 2nd question 5 square is not there but when you are solving the same question it become 5 square?

[@AnilKumar-uq3yp]

Fantastic

[@rituagrawal5648]

Sir in 9:37 how x=0 it should be +8

[@fdsbfds]

Aree -8 is multiplied by x therefore -8 is taken to the right side and multiplied by 0=0

[@sameeksha1048]

Confusion hi confusion hai

[@rksingh2320]

Excellent sir sir please if possible make video of Linear in two variable ch4 class 9

[@Balaram9853]

Sir your explanation is soo easy to understand but by your teaching i am able to do your all sum but sir your 7 is like a arrow mark and i confused for this

[@omniboyyash4398]

Sir agar hum aap quostion karte ho please sir ache see explain kariye . Please sir don't do step marking because I am not understanding what ever question you are explaining

[@ashutoshkivines7047]

Who love teaching from this sir #desicomedyfactory

[@sandeeppanday6641]

I totally interested to teach with sir but there is mistake in two questions who sir give for do own self

[@ajayguptagupta9178]

Can't we subtract both the equation

[@sharmapp701]

Next chapter ki video ....kahaaa h

[@r.8572]

Sir 6(4/3)square 3=128/9???????how I m not understanding .plz give the full solution Sir.👈😊

[@pearl_yyy]

Cut by 3

[@sarthakchauhan2140]

I am still not getting answer of the first question Please help me Edit: I got it just after writing this comment

[@akanini2100]

Super

[@piyush6904]

Division mae x^2 ki jagah 2 aana tha I think example mae

[@maazansari4538]

Sir 9:30 pe -8x equal to 0 phir X equal to 0 kaise aaya

[@hkpuneet6789]

Bhai 0/-8 = 0

[@stygian9232]

Sir.... wouldn't -8x=0 be -8?

[@abhishekanand6320]

No it would be positive 8 as u are shifting it to the right side

[@alllhappy159]

No it will be 0 upon 8 as on LHS -8 is multipying with x

[@dr1pwoo197]

Sir I have a doubt in the 1st that you made us do by own..in that question where did you solve -20 I can't see it in the 3rd statement

[@saimatasneem5852]

Same here

[@TabrezAlam-jq3iu]

Sir mast samjharahen hai

[@tejaswineeghosh745]

A lots of thanku sir.your explanation is marvellous.

[@rajshrir3000]

I couldn't find the lesson on algebraic identities

[@agk1372]

In question - if x = 4/3 is a zero of the polynomial f (x) = 6.................................. wale question mai he has done lots of mistakes dont follow him

[@prabhulalverma3515]

sir aap question kuch aur dete ho aur us question ko jab explain karte ho tab kuch aur question karte ho just like in question no. 2. aapne polynomial f(x) ki 2nd term mein to likha hi nahi ki x ki power 2 hai.

[@omniboyyash4398]

Sir I don't understand your first

[@ABHISHEKKUMAR-kf5bp]

Sir dusra question jo diye hai or jo solve kiye hai vo dono alag hai

[@sunderpattipakridayal962]

Time 1:46

[@kami-sama4509]

Sir at 1:51 you didn't transfer -20 to the RHS and my answer is k= 41/3 which is correct I suppose...

[@ajayguptagupta9178]

Sir first question main aapne 20 ko solve nahi kiya

[@sandeeppanday6641]

Question galat h sir

[@drrksparmar5624]

Sir in most of the questions square miss ho raha hai

[@divyaupadhyay4563]

Aapne 21 26 p wrong kiya h

[@divyaupadhyay4563]

Sir aapne baht questions wrong h isse hamara maths ka syllabus wrong and weak ban sakta h
