Answer:
select -3 and 2
Step-by-step explanation:
f(x)=g(x) means set them equal and solve for x
x^2+2x-8=-x^2+4
Add x^2 on both sides and subtract 4 on both sides.
2x^2+2x-12=0
Divide both sides by 2
x^2+x-6=0
Think of two numbers that multiply to be -6 and add up to be 1
that is 3 and -2
so The factored form is (x+3)(x-2)=0
So x=-3 or x=2
