7 y^{3} - 34 y^{2} - 5 y = 0

y = 0, y = - \frac{1}{7}, y = 5

Decimal Notation

y = 0, y = - 0.14285 \dots, y = 5

Solution steps

7 y^{3} - 34 y^{2} - 5 y = 0

Factor

7 y^{3} - 34 y^{2} - 5 y : y (7 y + 1) (y - 5)

y (7 y + 1) (y - 5) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y = 0 or 7 y + 1 = 0 or y - 5 = 0

Solve

7 y + 1 = 0 : y = - \frac{1}{7}

Solve

y - 5 = 0 : y = 5

The solutions are

y = 0, y = - \frac{1}{7}, y = 5

2 k^{3} - 3 k + 1 = 0

7 (7 x^{2})^{2} = 4 (7 x^{2}) + 1

x, x^{5} = y^{- 4}

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

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