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

x = 1, x = - 2

Solution steps

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

Factor

2 x^{3} - 6 x + 4 : 2 (x - 1)^{2} (x + 2)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 1 = 0 or x + 2 = 0

Solve

x - 1 = 0 : x = 1

Solve

x + 2 = 0 : x = - 2

The solutions are

x = 1, x = - 2

x^{4} + 9 x^{3} + 23 x^{2} + 3 x - 36 = 0

6 x^{5} + 11 x^{4} - 39 x^{3} - 41 x^{2} + 45 x + 18 = 0

5 x^{3} = 320

x^{3} - 5 x^{2} - 4 x + 20

x^{3} - 2 x^{2} + x - 2
