sqrt(x+15)=x+3

Solution

x + 15 = x + 3

Solution

x = 1

Solution steps

x + 15 = x + 3

Square both sides:

x + 15 = x^{2} + 6 x + 9

x + 15 = x^{2} + 6 x + 9

Solve

x + 15 = x^{2} + 6 x + 9 : x = 1, x = - 6

x = 1, x = - 6

Verify Solutions:

x = 1

True

, x = - 6

False

The solution is

x = 1
