x-2=sqrt(9x+4)

Solution

x - 2 = 9 x + 4

Solution

x = 13

Solution steps

x - 2 = 9 x + 4

Square both sides:

x^{2} - 4 x + 4 = 9 x + 4

x^{2} - 4 x + 4 = 9 x + 4

Solve

x^{2} - 4 x + 4 = 9 x + 4 : x = 13, x = 0

x = 13, x = 0

Verify Solutions:

x = 13

True

, x = 0

False

The solution is

x = 13
