sqrt(x^2-12)=sqrt(x)

x^{2} - 12 = x

x = 4

Solution steps

x^{2} - 12 = x

Square both sides:

x^{2} - 12 = x

x^{2} - 12 = x

Solve

x^{2} - 12 = x : x = 4, x = - 3

x = 4, x = - 3

Verify Solutions:

x = 4

True

, x = - 3

False

The solution is

x = 4

y^{\frac{1}{3}} = 5

x, x = e^{9}

\frac{4}{5} = 1 - x^{2}

0 = 16 - x^{2}
