%28x+%2B+4%29%5E2+=+16
sqrt%28%28x+%2B+4%29%5E2%29+=+sqrt%2816%29Take the square root of both sides.
x%2B4=4 and x%2B4=-4 since both 4%2A4=%28-4%29%2A%28-4%29=16
Solve the two equations for x.
x%2B4=4
x%2B4-4=4-4
highlight%28x=0%29
x%2B4=-4
x%2B4-4=-4-4
highlight%28x=-8%29
Your two solutions are x=0 and x=-8.
