Favor out a-1 as long as you do it to the whole problem it is now equivalent then just worry about factoring the new product
-1(8x^2+X-9)
(8x+9)((X-1)
8x+9=0
Subtract 9 divide by 8
X=-9/ 8 answer
X-1=0 X=1 answer

What are the x-intercepts of the parabola x2 + 4x −12?
vladimir1956 [14]
When you factor the parabola you get 
(x+6)(x-2)
set each of these equal to zero 
x+6=0       x-2=0
solve for x 
x=-6          x=2
these are your x-intercepts
(-6,0) and (2,0)
