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

s = - 2, s = - 1, s = 1

Solution steps

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

Factor

s^{3} + 2 s^{2} - s - 2 : (s + 2) (s + 1) (s - 1)

(s + 2) (s + 1) (s - 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

s + 2 = 0 or s + 1 = 0 or s - 1 = 0

Solve

s + 2 = 0 : s = - 2

Solve

s + 1 = 0 : s = - 1

Solve

s - 1 = 0 : s = 1

The solutions are

s = - 2, s = - 1, s = 1

(3 x - 1)^{6} = 1

x^{3} (2 x^{2} + 24) = 128 x

(x - 7)^{3} = 8

x^{2} 8 x - 4 = 0

x, 2 y = x^{3}
