sqrt(2x-4)=x-2

2 x - 4 = x - 2

x = 4, x = 2

Solution steps

2 x - 4 = x - 2

Square both sides:

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

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

Solve

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

x = 4, x = 2

Verify Solutions:

x = 4

True

, x = 2

True

The solutions are

x = 4, x = 2

6 L^{\frac{7}{2}} = 48 L^{2}

- 10 + x = - 6

x + 1 = 2 - x - 1

x - 9 - x = - 1

- 5 = 5 x - 1 - x
