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

x = - 9, x = - 1, x = 1

Solution steps

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

Factor

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

(x + 9) (x + 1) (x - 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 9 = 0 or x + 1 = 0 or x - 1 = 0

Solve

x + 9 = 0 : x = - 9

Solve

x + 1 = 0 : x = - 1

Solve

x - 1 = 0 : x = 1

The solutions are

x = - 9, x = - 1, x = 1

(4 x + 8)^{2} (2 x - 6)^{3} = 0

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

x, 7 x^{6} = y^{2} x

x, x^{4} - 4 x^{2} - y = 0

- 5 s s^{2} - 16 + 8 s + 4 = 1 s - 4
