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}.

[@nerixvallar2537]

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

[@comoyun]

yeah, the most satisfying part.

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

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!

[@corijerivero7132]

Very helpful teacher! Thank you!

[@MathTeacherGon]

Glad it was helpful!

[@flowwolfvibez]

I really appreciate people like you making videos like this

[@MathTeacherGon]

wow..thank you!!!

[@Nobody09618]

Thanks

[@Nobody09618]

Please make videos on inequalities and equations reducible to quadratic form

[@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

[@itsmevina0722]

i get it naaa, thank u so much po😭

[@michaelhharmon3519]

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

[@avarevar3308]

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..👍

[@lunar-e.6620]

👍👍👍

[@MathTeacherGon]

thanks!

[@user-nc2tx4fh1h]

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.

Hi sir panu po kung blank yung constant term

[@jackielyncrizaldo6845]

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

[@russelandreiadarne2212]

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

[@GiuseppeAugustineMErada]

Sir how can I solve y squared +8y=0?

[@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

[@KarlStephenLPerez]

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

[@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?

[@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.

[@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

[@dareenshehabeddine2326]
