sqrt(20-x)=x-8

Solution

20 - x = x - 8

Solution

x = 11

Solution steps

20 - x = x - 8

Square both sides:

20 - x = x^{2} - 16 x + 64

20 - x = x^{2} - 16 x + 64

Solve

20 - x = x^{2} - 16 x + 64 : x = 11, x = 4

x = 11, x = 4

Verify Solutions:

x = 11

True

, x = 4

False

The solution is

x = 11
