dude this channel is like the only youtube channel to ever return value to its watchers i hop the tube pays u well khan u deserve every penny and then some

[@josea3300]

thanks man our teacher didn't really teach us this and still gave it for homework so thank you

[@theoddpirate6695]

Jose A same Actually I wasn’t just listening ( cus we had to design our notebook so I was busy )

[@fahadnasser2477]

how r u doing now

[@bryannguyen658]

The method he is using is FOIL (First, Outer, Inner, Last)

[@lamyaaa5003]

[@HappyPlaysWasTaken]

isnt that literally the exact same thing as the distributive property

[@mahibhatt4011]

Ok thanks

[@captainbube1217]

@@HappyPlaysWasTaken no its way more stupid and should be banned in schools.

[@screamingslave99]

i wish more teachers taught like this. the colors are awesome. its been a long time since i've been in school but this video is great! i wish i had this in school! keep up the good work sir!

Are you alive?

[@whosfredol5194]

Oh, hello fellow student... it seems I was only a mere 2 year old when you commented this; I guess schools brings the internet from old of ages back thogethere.

[@the_rusty_potato2643]

No because 12+2 = 14. Not thirteen.

[@unknownman6848]

What my teacher teached us: 1+1=2 Vs What coms in exam: (a+b)(a+b)

[@talyahany1751]

Thank u so much U explained what a teacher explains in like a month

[@Tehcarp]

Your use of colour is, in my mind, what stands out between your tutorials and those of others. This video is a good example of what works, though there could still be more colour used in a way that maintained the sensibility, and improved the understanding of students of the material.

[@RobinUngureit]

Thank you so much. I am currently going to an online college, and I haven't taken Algebra in years, watching you go through the problems enables me to better understand what it is that i am doing. thanks again =)

Wow thank you soo much this was our next lesson and since now that I learned it in advance I probably wont have any problems with catching up in my class 😁😁 thanks so much

In the beginning of the video i was like hold on!! But then i remembered i could pause the video lol XD

this video of 10 minutes is better than my professor of math like suscribe.

[@raphaelleahpar9216]

Is this for 1st year highschool?

[@johnralph8213]

Or ... Step 1 : Square of its first term . Step 2 : Product of its terms. Step 3 : Square of its last term. Simple .

[@Pikachu-ho8rp]

nope. square the first term. product of both terms TIMES TWO. square the last term.

[@hexagon1421]

You mean FOIL?

[@taylorstan8411]

thanks keep sharing your knowledge there are many people who needs your hlp keep doing it god bless

[@mustaferoble]

thanks you have more information

[@markvincentordiz]

although the same result, 2(3x)(-7) = -42x, i was taught 2[(3x)(-7)] = -42x.

[@mattc7328]

Where's the video on Factor Special Products (Basic)? Example: x​2​​−d=(x+6)(x+c)

[@amyvergara6063]

Now i can pass the exam

[@fate2019]

there are easier methods especially for special products but anyways, thanks!

[@allyzamariecalsado1847]

how about this cab you solve it (2a-7)(2a-7)

[@humzatariq1604]

2a(2a-7) = 4a^2 - 14a -7(2a-7) = -14a + 49 Therefore; 4a^2 - 14a -14a +49 (or 7^2) = 4a^2 -28a + 7^2

it's on the website khanacademy search for it

[@aiyasiamanalo-mr7rx]

Its just like polynomials but instead its binomials which you need to multiply?

[@xxgamer_lucyxx1214]

Still don't get it but I'll try

[@bloroxcleach896]

You can use punnet square method for the first problem.

FOIL METHOD AND VERTICAL METHOD AND HORIZONTAL METHOD...

[@patriciamaeperez7168]

How about this.... (3-4m)² , (8-3x) (8+3x) , and (2t-1) (t+5) ?? PS: Can you solve this.. pretty please.??

how do you do this? 4(x+6)(x−5)

[@squareball7017]

x2 + 1x - 30 x2 = x squared

[@someoneelsewhere9519]

Joker 4life associative property. distribute the 4 among the first binomial, then distribute that amongst the second binomial

[@humzatariq1604]

4(x+6) (4x+24) (x-5) 4x(x-5) = 4x^2 -20x 24(x-5) 24x - 120 = 4x^2 - 20x +24x - 120 = 4x^2 +4x -120
