factor

x^{3} + x^{2} + x + 1 = 0

x = - 1, x = i, x = - i

Solution steps

x^{3} + x^{2} + x + 1 = 0

Factor

x^{3} + x^{2} + x + 1 : (x + 1) (x^{2} + 1)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x^{2} + 1 = 0

Solve

x + 1 = 0 : x = - 1

Solve

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

The solutions are

x = - 1, x = i, x = - i

x^{4} - x^{3} - 30 x^{2}

2 x^{4} + 5 x^{3} - 23 x^{2} + 10 x = 0

x^{3} + 9 x^{2} + 20 x = 0

12 x^{3} - 36 x = 0

2 x^{3} - 3 x^{2} - 32 x - 15 = 0
