x^{3} - 31 x - 30 = 0

x = - 1, x = - 5, x = 6

Solution steps

x^{3} - 31 x - 30 = 0

Factor

x^{3} - 31 x - 30 : (x + 1) (x + 5) (x - 6)

(x + 1) (x + 5) (x - 6) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x + 5 = 0 or x - 6 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x + 5 = 0 : x = - 5

Solve

x - 6 = 0 : x = 6

The solutions are

x = - 1, x = - 5, x = 6

12000 x^{3} - 85800 x^{2} - 300000

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

- 0.024 = x^{4} - 2 \cdot x^{5} - x^{6}

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

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