Answer:
x = 2, x = -6
Step-by-step explanation:
[tex]x^2+4x-4=8[/tex]
Subtract 8 from both sides.
[tex]x^2+4x-4-8=8-8[/tex]
Simplify.
[tex]x^2+4x-12=0[/tex]
Solve with quadratic formula.
a = 1
b = 4
c = -12
I do not have time to show work for quadratic formula parts.
I am so sorry for this inconvenience.
