0 = x^{3} + x^{2} - 9 x - 9

x = - 1, x = - 3, x = 3

Solution steps

0 = x^{3} + x^{2} - 9 x - 9

Switch sides

x^{3} + x^{2} - 9 x - 9 = 0

Factor

x^{3} + x^{2} - 9 x - 9 : (x + 1) (x + 3) (x - 3)

(x + 1) (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x + 3 = 0 or x - 3 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = - 1, x = - 3, x = 3

3 x^{4} = 24 x

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

0 = x^{4} - 3 x^{3} + 6 x

r^{3} - 3 r^{2} + 2 r = 0

b^{3} = 2
