sqrt(2x+30)=x+3

Solution

2 x + 30 = x + 3

Solution

x = 3

Solution steps

2 x + 30 = x + 3

Square both sides:

2 x + 30 = x^{2} + 6 x + 9

2 x + 30 = x^{2} + 6 x + 9

Solve

2 x + 30 = x^{2} + 6 x + 9 : x = 3, x = - 7

x = 3, x = - 7

Verify Solutions:

x = 3

True

, x = - 7

False

The solution is

x = 3
