sqrt(30-2x)=x+9

Solution

30 - 2 x = x + 9

Solution

x = - 3

Solution steps

30 - 2 x = x + 9

Square both sides:

30 - 2 x = x^{2} + 18 x + 81

30 - 2 x = x^{2} + 18 x + 81

Solve

30 - 2 x = x^{2} + 18 x + 81 : x = - 3, x = - 17

x = - 3, x = - 17

Verify Solutions:

x = - 3

True

, x = - 17

False

The solution is

x = - 3
