2 y (y - 9) (y + 4) = 0

y = 0, y = 9, y = - 4

Solution steps

2 y (y - 9) (y + 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y = 0 or y - 9 = 0 or y + 4 = 0

Solve

y - 9 = 0 : y = 9

Solve

y + 4 = 0 : y = - 4

The solutions are

y = 0, y = 9, y = - 4

4 x^{3} - 12 x^{2} + 8 x = 0

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

2 x^{4} - 15 x^{3} + 18 x^{2} = 0

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

4 x^{4} + 10 x^{3} = 6 x^{2} + 15 x
