9 x - x^{3} = 0

x = 0, x = - 3, x = 3

Solution steps

9 x - x^{3} = 0

Factor

9 x - x^{3} : - x (x + 3) (x - 3)

- x (x + 3) (x - 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 3 = 0 or x - 3 = 0

Solve

x + 3 = 0 : x = - 3

Solve

x - 3 = 0 : x = 3

The solutions are

x = 0, x = - 3, x = 3

12 x^{5} = 20 x^{4} + 8 x^{2} - 16

5.3 \cdot 1 0^{- 9} = (y) (2 y)^{2}

x^{4} - 98715 x^{2} + 1040 = 0

3 x^{3} - 243 x = 0

x^{3} + 2 x^{2} - 21 x + 35 = 0
