3 y^{3} - 20 y^{2} - 7 y = 0

y = 0, y = - \frac{1}{3}, y = 7

Decimal Notation

y = 0, y = - 0.33333 \dots, y = 7

Solution steps

3 y^{3} - 20 y^{2} - 7 y = 0

Factor

3 y^{3} - 20 y^{2} - 7 y : y (3 y + 1) (y - 7)

y (3 y + 1) (y - 7) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y = 0 or 3 y + 1 = 0 or y - 7 = 0

Solve

3 y + 1 = 0 : y = - \frac{1}{3}

Solve

y - 7 = 0 : y = 7

The solutions are

y = 0, y = - \frac{1}{3}, y = 7

4 t^{3} - 12 t^{2} - 72 t + 25 = 25

4 x^{3} - 5 x + 2 = 24

2 x^{3} - 6 x^{2} + 13 x - 14 = 0

x^{3} = - 1 - i

7 x^{6} + 35 x^{4} = 42 x^{5}
