Solve x^2 +4-4=8 for x
x=-6 or x=2
x=-2+/- 2 (square root) 2
x=-2 or x =6
x=2+/-2 (square root)2

If anyone has done the algebra 2 chaos theory portfolio would you be wiling to me? i kind of know what i'm doing i just don't know if i'm doing it right.

Can someone me with this problem i don't understand i need
