3 x^{5} + x^{4} - 9 x^{3} - 9 x^{2} - 2 x = 0

x = 0, x = - 1, x = - \frac{1}{3}, x = 2

Decimal

x = 0, x = - 1, x = - 0.33333 \dots, x = 2

Solution steps

3 x^{5} + x^{4} - 9 x^{3} - 9 x^{2} - 2 x = 0

Factor

3 x^{5} + x^{4} - 9 x^{3} - 9 x^{2} - 2 x : x (x + 1)^{2} (3 x + 1) (x - 2)

x (x + 1)^{2} (3 x + 1) (x - 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 1 = 0 or 3 x + 1 = 0 or x - 2 = 0

Solve

x + 1 = 0 : x = - 1

Solve

3 x + 1 = 0 : x = - \frac{1}{3}

Solve

x - 2 = 0 : x = 2

The solutions are

x = 0, x = - 1, x = - \frac{1}{3}, x = 2

x + x^{3} = 4

x^{3} + 125 = 0

x^{4} + 13 x^{2} + 40 = 0

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

- x^{3} + 6 x^{2} + 15 x + 8
