x = - 1, x = \frac{- 4 + 2}{4}, x = - \frac{4 + 2}{4}

Decimal Notation

x = - 1, x = - 0.64644 \dots, x = - 1.35355 \dots

Solution steps

Take both sides of the equation to the power of

3 : x + 1 = 8 x^{3} + 24 x^{2} + 24 x + 8

x + 1 = 8 x^{3} + 24 x^{2} + 24 x + 8

Solve

x + 1 = 8 x^{3} + 24 x^{2} + 24 x + 8 : x = - 1, x = \frac{- 4 + 2}{4}, x = - \frac{4 + 2}{4}

x = - 1, x = \frac{- 4 + 2}{4}, x = - \frac{4 + 2}{4}

Verify Solutions:

x = - 1

True

, x = \frac{- 4 + 2}{4}

True

, x = - \frac{4 + 2}{4}

True

The solutions are

x = - 1, x = \frac{- 4 + 2}{4}, x = - \frac{4 + 2}{4}

x + 5 = 7

x^{\frac{3}{5}} = - 8

x - x - 1 = 13

x - x = 2

x - x = 0
