y^{3} - 10 y^{2} + 21 y = 0

y = 0, y = 3, y = 7

Solution steps

y^{3} - 10 y^{2} + 21 y = 0

Factor

y^{3} - 10 y^{2} + 21 y : y (y - 3) (y - 7)

y (y - 3) (y - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y = 0 or y - 3 = 0 or y - 7 = 0

Solve

y - 3 = 0 : y = 3

Solve

y - 7 = 0 : y = 7

The solutions are

y = 0, y = 3, y = 7

x^{6} - x^{3} + 1 = 0

s^{3} + 9 s^{2} + 15 s + 5 = 0

2 x^{3} - 4 x^{2} - 10 x + 20

1.58 = (1 + \frac{x}{2})^{4}

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