(x^2+2x)^{1/3}=2

(x^{2} + 2 x)^{\frac{1}{3}} = 2

x = 2, x = - 4

Solution steps

(x^{2} + 2 x)^{\frac{1}{3}} = 2

Take both sides of the equation to the power of

3 : x^{2} + 2 x = 8

x^{2} + 2 x = 8

Solve

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

x = 2, x = - 4

Verify Solutions:

x = 2

True

, x = - 4

True

The solutions are

x = 2, x = - 4

x + 3 - x - 3 = 3

x - 2 + x = 8

9 x^{2} + 16 = 5

x^{2} + x + 1 - 1 = x

x - 169 - x^{2} = 17
