Question

Solve x2 + 10x + 12 = 36 for x. x = –12 or x = 2 x = –11 or x = 1 x = –2 or x = 12 x = –1 or x = 11

Answer 1

So its x to the second power + 10x + 12 = 36
What I did was subtracted 12 from 36 to get 24
then when on from there to find the x valuse
x=2
x=-12
I'm sorry if its wrong I did it all in my head

Answer 2

option 1st is correct

x = -12 or x = 2

Explanation:

Solve:

`x^2+10x+12=36`

Subtract 36 from both sides we have;

`x^2+10x-24=0`

Split the middle term we have;

`x^2+12x-2x-24=0`

then;

`x(x+12)-2(x+12)=0`

Take x+12 common we have;

`(x+12)(x-2)=0`

By zero product property, if ab =0 then a = 0 or b = 0

then;

x+12 = 0 or x -2 =0

⇒x = -12 or x = 2

therefore, the solutions are x = -12 or x = 2
