2 x^{3} - 6 x^{2} - 6 x + 18 = 0

x = 3, x = - 3, x = 3

Decimal Notation

x = 3, x = - 1.73205 \dots, x = 1.73205 \dots

Solution steps

2 x^{3} - 6 x^{2} - 6 x + 18 = 0

Factor

2 x^{3} - 6 x^{2} - 6 x + 18 : 2 (x - 3) (x + 3) (x - 3)

2 (x - 3) (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 3 = 0 or x + 3 = 0 or x - 3 = 0

Solve

x - 3 = 0 : x = 3

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = 3, x = - 3, x = 3

9 x^{4} - 18 x^{2} + 5 = 0

m^{3} - 27 = (m - 3)

24 x^{3} - 24 x^{2} = 0

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

y^{3} - 2 y^{2} + y = 0
