solve for

x, 3 x^{3} + x^{2} - 8 x + 4 = 0

x = 1, x = \frac{2}{3}, x = - 2

Decimal Notation

x = 1, x = 0.66666 \dots, x = - 2

Solution steps

3 x^{3} + x^{2} - 8 x + 4 = 0

Factor

3 x^{3} + x^{2} - 8 x + 4 : (x - 1) (3 x - 2) (x + 2)

(x - 1) (3 x - 2) (x + 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x - 1 = 0 or 3 x - 2 = 0 or x + 2 = 0

Solve

x - 1 = 0 : x = 1

Solve

3 x - 2 = 0 : x = \frac{2}{3}

Solve

x + 2 = 0 : x = - 2

The solutions are

x = 1, x = \frac{2}{3}, x = - 2

\frac{5 x - 6}{3} = x^{5}

f = f^{5}

d^{3} = 729

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

5 x^{3} - 6 x^{2} - 5 x + 6 = 0
