Solving Quadratic Equations by Completing the Square - Math Teacher Gon

[@nerixvallar2537]

i appreciate this but there is still one thing we need here, the checking of each equations :)

[@comoyun]

yeah, the most satisfying part.

[@yvxann]

My answer is x=2 square root of 17+6 1 x=-2square root of 17+6 2 X²+12×+36=32+36 Cancel out radical and ² and then find square root of 68 x+6=±2 square root of 17+6 transpose 6 x=±2 square root of17+6

[@svenkonings9822]

U forgot a small detail: the right hand side should be -32 + 36, So therefore (x + 6)² = 4. x + 6 = ± square root of 4 which is ±2. X = -6 ± 2

[@kazensko]

Man completing the square is the hardest out of all the ways to solve quadratic equations.

[@itsmevina0722]

i get it naaa, thank u so much po😭

[@flowwolfvibez]

I really appreciate people like you making videos like this

[@MathTeacherGon]

wow..thank you!!!

[@louisramos4290]

There is a market for your math tutoring skills in the USA and even "teacher positions " that would kill to have you. However, many students in America are on vacation going to school so honestly believe you would benefit from Tutoring better economically here. Days of life pass fast,encourage you to offer service via net to colleges,charter schools,etc., so you don't have to deal with office politics, asshole kids, or arrogant administrations. Good Luck Mi Hermano!

X² + 12x + 32 = 0 X² + 12x + 36 = -32 + 36 (X +6)² = +- 4 (with square root) X + 6 = +- 2 X = - 2-6 | X = +2 - 6 X= -8 | X = -4 Check my answers if u can thank for ur teaching..👍

[@Akiesha-n5n]

No you're wrong - 32+36 is 4 not-4 cause 36 is positive and it is bigger than - 32. So you should copy the sign

[@michaelhharmon3519]

The values of x in given equation for the assignment are x = ( - 34, - 38)

[@KW-gb9cd]

I solved that last one in my head using the AC method; it factored out to (x + 4)(x + 8), and the values of x were {-4, -8}.

[@Nobody09618]

8:58 The solution set is (-8,-4)

[@henrystudiosyt]

What if without any constant?

[@snitchshinshi603]

The answer is x= -4 or x= -8 In your assignment right? Please respond if my answer is correct thankyou!

[@miruuin7098]

We have the same answer pooo❤❤❤

[@ericagapay9245]

Same Tayo Ng answer

[@Nobody09618]

Please make videos on inequalities and equations reducible to quadratic form

[@corijerivero7132]

Very helpful teacher! Thank you!

[@MathTeacherGon]

Glad it was helpful!

[@Nobody09618]

Thanks

[@davidmckee533]

nice i like this video. I would like to see how it relates the graph of the equation . also the previous comment mentioned proving the answer would help. in complete understanding. I will be watching more of the videos . very nicely done though.

[@MathTeacherGon]

Will upload soon

x²+12x+32=0 x²+12x+_=-32+_ (12÷2)² 6²=36 x²+12x+36=-32+36 √(x+6)²=√-4(square x+6=+-2 x=2-6. x=-2-6 x=-4. x=-8

[@GenePrado-v9n]

What’s the answer of this equation. I tried to solve it but not so sure if my answer is correct. (X+3) (X-3)=8 Thanks

[@svenkonings9822]

x² - 9 = 8. x² = 17. x is the square root of 17.

[@russelandreiadarne2212]

SIR THIS IS MY ANSWER FOR YOU'RE ASSIGMENT X= -34 and x= -38.

[@jackielyncrizaldo6845]

Paano po if d pedeng i divide oml dko ma gets po un

[@themathacademy1446]

Nice explanation !

[@MathTeacherGon]

Glad you liked it!

[@EmmanuelchenCabibil-g8z]

my answer on assignment are x=4 and -8

[@DarianVideoMaker2007]

x=8 or x=4

[@snitchshinshi603]

The sign should be negative right? Cuz Postive2 minus 6 is negative 4 And negative2 and negative 6 would be negative 8. Am I right?

[@erlindoisid1062]

X1=√2-6 X2=-√2-6

[@jerrypaquette5470]

Using the quadratic formula is a much easier way.

[@svenkonings9822]

But quadratic formula is derivated from Completing the Square

[@jerrypaquette5470]

That is true, but since the formula has been derived, why go backwards use completing the square.

[@Trihsdalanon]

Hi sir panu po kung blank yung constant term

[@terenceguerra-wb5uq]

X=-8. x=-4

[@MathTeacherGon]

thank you!!!

[@aoirou321]

Uhm sir how did it become 16 in question number 2.?

[@nurseryrhymes143.]

because (-4)² is 16 because it multiply to it self. -4•-4 and negative • negative is positive😁

[@dareenshehabeddine2326]

x=_2 or x=-10

[@MathTeacherGon]

very good

[@snitchshinshi603]

Can I ask? how did it became x=-2 or x=-10? Cuz my answer is x=-4 and x=-8

Bat samen may checking? 😢

Paano po kapag 10? Ano pong ilalagay sa square root niyo, please reply po. Need na need ngayon sa performance task😭😭😭😭🙏🙏🙏🙏

Kunin mo square root ni 10 (10×10)
