answer: %28u-5%29%5e2-16=0 start with the given equation.

%28u-5%29%5e2=0%2b16add 16 to both sides.

%28u-5%29%5e2=16 combine like terms.

x-5=%22%22%2b-sqrt%2816%29 take the square root of both sides.

u-5=sqrt%2816%29 or u-5=-sqrt%2816%29 break up the "plus/minus" to form two equations.

u-5=4 or u-5=-4 take the square root of 16 to get 4.

u=5%2b4 or u=5-4 add 5 to both sides.

u=9 or u=1 combine like term

so the solutions are u=9 or u=1.
