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

x = \frac{2}{5}, x = - 1, x = 1

Decimal Notation

x = 0.4, x = - 1, x = 1

Solution steps

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

Factor

5 x^{3} - 2 x^{2} - 5 x + 2 : (5 x - 2) (x + 1) (x - 1)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

5 x - 2 = 0 : x = \frac{2}{5}

Solve

x + 1 = 0 : x = - 1

Solve

x - 1 = 0 : x = 1

The solutions are

x = \frac{2}{5}, x = - 1, x = 1

(2 + 3) \cdot x^{4} = 20

15 x^{4} - 20 x^{3} = 0

x^{3} - 11 x^{2} + 30 = 0

M = (x + 5) (x - 5) (x^{2} + 25) + 625

2 x^{4} = + 6 (0.6 - 4)
