2 x^{3} - 14 x^{2} + 2 x - 14 = 0

x = 7, x = i, x = - i

Solution steps

2 x^{3} - 14 x^{2} + 2 x - 14 = 0

Factor

2 x^{3} - 14 x^{2} + 2 x - 14 : 2 (x - 7) (x^{2} + 1)

2 (x - 7) (x^{2} + 1) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 7 = 0 or x^{2} + 1 = 0

Solve

x - 7 = 0 : x = 7

Solve

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

The solutions are

x = 7, x = i, x = - i

24 x^{3} + 46 x^{2} + 9 x - 9 = 0

r^{4} + 6 r^{3} + 17 r^{2} + 22 r + 14 = 0

x^{3} - x^{2} - 37 x - 35

x^{3} + 5 = 6 x^{2} + 3 x

n^{3} + n^{2} - 6 n = 0
