3%28x-4%29%5E2%2B5=20

3%28x-4%29%5E2=20-5

3%28x-4%29%5E2=15

%28x-4%29%5E2=15%2F3

%28x-4%29%5E2=5

x-4=%22%22%2B-sqrt%285%29

x-4=sqrt%285%29 or x-4=-sqrt%285%29

x=4%2Bsqrt%285%29 or x=4-sqrt%285%29


=======================================================

The two exact solutions are x=4%2Bsqrt%285%29 or x=4-sqrt%285%29
