- 2 x (x + 7) (x^{2} - 11) = 0

x = 0, x = - 7, x = - 11, x = 11

Solution steps

- 2 x (x + 7) (x^{2} - 11) = 0

Factor

- 2 x (x + 7) (x^{2} - 11) : - 2 x (x + 7) (x + 11) (x - 11)

- 2 x (x + 7) (x + 11) (x - 11) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 7 = 0 or x + 11 = 0 or x - 11 = 0

Solve

x + 7 = 0 : x = - 7

Solve

x + 11 = 0 : x = - 11

Solve

x - 11 = 0 : x = 11

The solutions are

x = 0, x = - 7, x = - 11, x = 11

x^{3} - x^{2} + 5 x - 5 = 0

x^{3} - 4 x^{2} - x - 4 = 0

20 x^{2} - 32 x - 2 x^{3} = 0

(x + 4)^{3} - 9 x = 36

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