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

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

x = - 1, x = 5

Solution steps

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

Expand

2 (x + 1) : 2 x + 2

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

Square both sides:

4 x^{2} + 8 x + 4 = 5 x^{2} + 4 x - 1

4 x^{2} + 8 x + 4 = 5 x^{2} + 4 x - 1

Solve

4 x^{2} + 8 x + 4 = 5 x^{2} + 4 x - 1 : x = - 1, x = 5

x = - 1, x = 5

Verify Solutions:

x = - 1

True

, x = 5

True

The solutions are

x = - 1, x = 5

y, x = 4 y

x + 30 = - x

x, 2 x - 9 x = - 9

400 = 0.3 x^{\frac{3}{4}}
