(2 x + 1)^{(\frac{1}{3})} - 3 = - 5

x = - \frac{9}{2}

Decimal Notation

x = - 4.5

Solution steps

(2 x + 1)^{(\frac{1}{3})} - 3 = - 5

Move

3

to the right side

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

Take both sides of the equation to the power of

3 : 2 x + 1 = - 8

2 x + 1 = - 8

Solve

2 x + 1 = - 8 : x = - \frac{9}{2}

x = - \frac{9}{2}

Verify Solutions:

x = - \frac{9}{2}

True

The solution is

x = - \frac{9}{2}

- 3 = x + 2

a = 4

x - 2 x + 1 = 1

3 x - 4 = 2 x - 5

x = x + 12
