Respuesta :
8x^2 would be you answer in all if it does not have details this would be your answer because it does not give you an = sign or a number for x.
So, x^2 + 7x + 12 =
( x + 4) ( x + 3)
x(x + 7) + 12
(x + 7/2)^2 - 1/4
or
that factors into (X - 4) x (X - 3)
you just divide the last number (12) into different things and see what will add together to get the middle number (-7)
-4 x -3 = 12 and -4 + -3 + -7
then you set the 2 factors = 0
X - 4 = 0 --> X = 4
X -3 = 0 --> X = 3
so 4 and 3 are the answers
I gave you the 2 ways I would answer this question, hope it helped : )
