s^{3} + 4 s^{2} + 5 s + 2 = 0

s = - 1, s = - 2

Solution steps

s^{3} + 4 s^{2} + 5 s + 2 = 0

Factor

s^{3} + 4 s^{2} + 5 s + 2 : (s + 1)^{2} (s + 2)

(s + 1)^{2} (s + 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

s + 1 = 0 or s + 2 = 0

Solve

s + 1 = 0 : s = - 1

Solve

s + 2 = 0 : s = - 2

The solutions are

s = - 1, s = - 2

z^{8} + 1 = 0

n^{4} + 15 n^{2} + 14 n + 15 = 0

2 x^{4} - x^{3} - 14 x^{2} - 5 x + 6 = 0

- 2 (x + 1)^{3} = 16

t^{3} - 6 t^{2} - 15 t + 40 = 0
