2sqrt(x)=2x-4

Solution

2 x = 2 x - 4

Solution

x = 4

Solution steps

2 x = 2 x - 4

Square both sides:

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

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

Solve

4 x = 4 x^{2} - 16 x + 16 : x = 4, x = 1

x = 4, x = 1

Verify Solutions:

x = 4

True

, x = 1

False

The solution is

x = 4

Popular Examples

1 = x^{\frac{3}{2}}

(x^2+5)(sqrt(x+2))=x

(x^{2} + 5) (x + 2) = x

sqrt(x^5+x^2)=pi

x^{5} + x^{2} = π

7 t + 2 = - 4

x^{3} - 2 = 5
