- 2 (5 x + 6) (x^{2} - 64) = 0

x = - 8, x = 8, x = - \frac{6}{5}

Decimal Notation

x = - 8, x = 8, x = - 1.2

Solution steps

- 2 (5 x + 6) (x^{2} - 64) = 0

Factor

- 2 (5 x + 6) (x^{2} - 64) : - 2 (x + 8) (x - 8) (5 x + 6)

- 2 (x + 8) (x - 8) (5 x + 6) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 8 = 0 or x - 8 = 0 or 5 x + 6 = 0

Solve

x + 8 = 0 : x = - 8

Solve

x - 8 = 0 : x = 8

Solve

5 x + 6 = 0 : x = - \frac{6}{5}

The solutions are

x = - 8, x = 8, x = - \frac{6}{5}

x^{4} + 3 = 0

(2^{24})^{\frac{1}{2}} = p^{4}

6 x^{2} - 3 x^{3} = 0

x^{3} + 2 x^{2} - 6 x - 12 = 0

(x + 1)^{3} = - 27
