25 x^{3} - 50 x^{2} - 4 x + 8 = 0

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

Decimal Notation

x = 2, x = - 0.4, x = 0.4

Solution steps

25 x^{3} - 50 x^{2} - 4 x + 8 = 0

Factor

25 x^{3} - 50 x^{2} - 4 x + 8 : (x - 2) (5 x + 2) (5 x - 2)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x - 2 = 0 : x = 2

Solve

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

Solve

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

The solutions are

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

3 - (x - 1)^{4} = 0

p^{3} - 49 p = 0

8 = x^{4} - 2 x^{2}

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

25 b^{2} + 35 b^{4} = 45 b^{5}
