x-3=sqrt(2x+2)

Solution

x - 3 = 2 x + 2

Solution

x = 7

Solution steps

x - 3 = 2 x + 2

Square both sides:

x^{2} - 6 x + 9 = 2 x + 2

x^{2} - 6 x + 9 = 2 x + 2

Solve

x^{2} - 6 x + 9 = 2 x + 2 : x = 7, x = 1

x = 7, x = 1

Verify Solutions:

x = 7

True

, x = 1

False

The solution is

x = 7
