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

f(x)=0

x=-8                 x=4

Step-by-step 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

step-by-step explanation:

step 1: solve one of the equations for one of the variables. let's solve the first equation for y:

step 2: substitute that equation into the other equation, and solve for x.

step 3: substitute x = 4 x = 4 x=4 into one of the original equations, and solve for y.
