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

x = 0, x = 4

Solution steps

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

Factor

5 x^{4} - 20 x^{3} : 5 x^{3} (x - 4)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 4 = 0

Solve

x - 4 = 0 : x = 4

The solutions are

x = 0, x = 4

y, y^{3} = x^{3} - x

- 4 x^{3} - 24 x^{2} - 72 x - 80 = 0

2 x^{3} - 9 x^{2} + 27 = 0

- x (x + 5) (x^{2} - 13) = 0

5 x^{3} + 35 x = 6 x^{2} + 42
