x=sqrt(x+6)

Solution

x = x + 6

Solution

x = 3

Solution steps

x = x + 6

Square both sides:

x^{2} = x + 6

x^{2} = x + 6

Solve

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

x = 3, x = - 2

Verify Solutions:

x = 3

True

, x = - 2

False

The solution is

x = 3

Popular Examples

((sqrt(x)))/((sqrt(1-x)))+((sqrt(1+x)))/((sqrt(x)))= 5/2

\frac{( x )}{( 1 - x )} + \frac{( 1 + x )}{( x )} = \frac{5}{2}

sqrt(x+10)-sqrt(x+19)=-1

x + 10 - x + 19 = - 1

sqrt(x^2-2x+1)-sqrt(x^2-4x+4)=x-3

x^{2} - 2 x + 1 - x^{2} - 4 x + 4 = x - 3

sqrt(x+7)-sqrt(3x-2)=1

x + 7 - 3 x - 2 = 1

x^{1/3}+2x^{2/3}-x=0

x^{\frac{1}{3}} + 2 x^{\frac{2}{3}} - x = 0
