b^{3} - 25 b = 0

b = 0, b = - 5, b = 5

Solution steps

b^{3} - 25 b = 0

Factor

b^{3} - 25 b : b (b + 5) (b - 5)

b (b + 5) (b - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

b = 0 or b + 5 = 0 or b - 5 = 0

Solve

b + 5 = 0 : b = - 5

Solve

b - 5 = 0 : b = 5

The solutions are

b = 0, b = - 5, b = 5

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

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

5 s^{3} + 7 s + 6.4 = 0

a^{4} = 10 a^{2}

2 (x^{2} - 2 x)^{2} - 5 (x^{2} - 2 x) = 7
