Answer:
The zeros are 1 and -6
Explanation:
f(x)=2x^2 + 10x – 12
Set the equation equal to zero
0 =2x^2 + 10x – 12
Divide each side by 2
0/2=2/2x^2 + 10/2x – 12/2
0 = x^2 +5x -6
Factor
What 2 numbers multiply to -6 and add to 5
6*-1 = -6
6-1 =5
(x+6) (x-1) =0
Using the zero product property
x+6 =0 x-1=0
x=-6 x=1
