x^{3} + x^{2} - x + 15 = 0

x = - 3, x = 1 + 2 i, x = 1 - 2 i

Solution steps

x^{3} + x^{2} - x + 15 = 0

Factor

x^{3} + x^{2} - x + 15 : (x + 3) (x^{2} - 2 x + 5)

(x + 3) (x^{2} - 2 x + 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 3 = 0 or x^{2} - 2 x + 5 = 0

Solve

x + 3 = 0 : x = - 3

Solve

x^{2} - 2 x + 5 = 0 : x = 1 + 2 i, x = 1 - 2 i

The solutions are

x = - 3, x = 1 + 2 i, x = 1 - 2 i

x^{3} - 12 x^{2} + 47 x - 60 = 0

3 q^{3} = - 8 + \frac{D}{A}

x^{3} - 15 x^{2} + 56 x = 0

y^{4} + 7 y^{2} - 144 = 0

2 (x^{2} - 5) (x^{2} + 100) = 0
