Solution

x + 81 + 9 = x

Solution

x = 19

Solution steps

x + 81 + 9 = x

Remove square roots

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

Solve

x + 81 = x^{2} - 18 x + 81 : x = 19, x = 0

x = 19, x = 0

Verify Solutions:

x = 19

True

, x = 0

False

The solution is

x = 19

Popular Examples

x^{\frac{1}{2}} = 4

5/(2+sqrt(x))= 13/6

\frac{5}{2 + x} = \frac{13}{6}

2 x + 1 = x - 1

x^2-sqrt(2x)+2=0

x^{2} - 2 x + 2 = 0

((sqrt(2x-3)))/((sqrt(x-1)))=2

\frac{( 2 x - 3 )}{( x - 1 )} = 2
