Question

For the function ​f(x)=x^{2} + 4x - 32 solve the following.​

f(x)=0

Answer 1

x=-8 x=4

Explanation:

x^2 + 4x - 32

We want to set this equal to zero

x^{2} + 4x - 32 =0

Factor this equation

what two numbers multiply together to equal -32 and add together to equal4

8 * -4 = -32

8+ -4 = 4

(x+8) ( x-4) =0

Using the zero product property

x+8 =0 x-4 =0

x+8-8=0-8 x-4+4=0+4

x=-8 x=4
