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

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

x = 4

Solution steps

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

Square both sides:

x^{2} - 4 x = 16 - 8 x + x^{2}

x^{2} - 4 x = 16 - 8 x + x^{2}

Solve

x^{2} - 4 x = 16 - 8 x + x^{2} : x = 4

x = 4

Verify Solutions:

x = 4

True

The solution is

x = 4

3 - x = 0

x + 1 + x + 13 = 6

\frac{2}{4 x - 3} = 1

x + 7 + x + 2 = 5
