30 x^{4} - 120 x^{3} = 0

x = 0, x = 4

Solution steps

30 x^{4} - 120 x^{3} = 0

Factor

30 x^{4} - 120 x^{3} : 30 x^{3} (x - 4)

30 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

4 x^{3} - 12 x^{2} - 9 x - 1 = 0

2 x^{3} + 3 x^{2} - 12 x + 1 = 0

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

H^{3} - 0.479 H^{2} + 0.01 = 0

x^{4} + 3 x^{2} + 6 = 0
