Question

I need help with this equation.
x^2+12x+36=25
I got -11, -1
I'm not sure if I placed the neg/pos signs incorrectly. . but, it's not an answer choice.

Answer 1

let me check that

Answer 2

okay would u wait 5 mins i willl give u answer

Answer 3

we can test your numbers.
For x=-1 x^2 = -1*-1 = 1
12 x is -12
and
1-12+36 simplifies to 36-11= 25 which matches
now let's test -11

Answer 4

-11*-11 = +121
12x is 12*-11 = -132
121-132+36 is 25
that also works

Answer 5

x^2+12x+36 =25
x^2 +12x +36-25=0
x^2 +12x +11=0
use the factorizing method
x^2 +x +11x +11=0
x(x+1) +11(x+1) =0
(x+11)(x+1)=0
either'
x+11=0 or x+1=0
x=-11 or x=-1
your answer is absolutely correct i m sure 100 %

Answer 6

@-EtherealEbullience match your answer with mine

Answer 7

. . . Nevermind, I got it. xD

Answer 8

when you solved this problem , you would do the following:
x^2+12x+36=25
add -25 to both sides
x^2+12x+36 -25 =25 - 25 and simplify to get
x^2 +12x +11 = 0 It is in standard form.

this factors: the 11 is 1*11
and the 1+11 is 12. This means we use 1 and 11 and write the factors

(x+11)(x+1)=0

to solve, either x+11 =0 or x+1 = 0
in the first case x+11=0 add -11 to both sides. we get x= -11
and for the second case x+1=0, add -1 to both sides. we get x=-1

Thank you, it was, I overlooked it.
