sqrt(2x+20)=x-2

Solution

2 x + 20 = x - 2

Solution

x = 8

Solution steps

2 x + 20 = x - 2

Square both sides:

2 x + 20 = x^{2} - 4 x + 4

2 x + 20 = x^{2} - 4 x + 4

Solve

2 x + 20 = x^{2} - 4 x + 4 : x = 8, x = - 2

x = 8, x = - 2

Verify Solutions:

x = 8

True

, x = - 2

False

The solution is

x = 8
