2 y^{3} - 17 y^{2} - 9 y = 0

y = 0, y = - \frac{1}{2}, y = 9

Decimal Notation

y = 0, y = - 0.5, y = 9

Solution steps

2 y^{3} - 17 y^{2} - 9 y = 0

Factor

2 y^{3} - 17 y^{2} - 9 y : y (2 y + 1) (y - 9)

y (2 y + 1) (y - 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

y = 0 or 2 y + 1 = 0 or y - 9 = 0

Solve

2 y + 1 = 0 : y = - \frac{1}{2}

Solve

y - 9 = 0 : y = 9

The solutions are

y = 0, y = - \frac{1}{2}, y = 9

x^{400} = 9^{1000}

4 x^{4} = 53 x^{2} - 49

4 x^{3} - x - 1 = 0

15 = x^{5}

t^{3} - 3 t^{2} + 2 t = 0
