sqrt(x+79)=x+7

Solution

x + 79 = x + 7

Solution

x = 2

Solution steps

x + 79 = x + 7

Square both sides:

x + 79 = x^{2} + 14 x + 49

x + 79 = x^{2} + 14 x + 49

Solve

x + 79 = x^{2} + 14 x + 49 : x = 2, x = - 15

x = 2, x = - 15

Verify Solutions:

x = 2

True

, x = - 15

False

The solution is

x = 2
