240 x - 60 x^{3} = 0

x = 0, x = - 2, x = 2

Solution steps

240 x - 60 x^{3} = 0

Factor

240 x - 60 x^{3} : - 60 x (x + 2) (x - 2)

- 60 x (x + 2) (x - 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x + 2 = 0 or x - 2 = 0

Solve

x + 2 = 0 : x = - 2

Solve

x - 2 = 0 : x = 2

The solutions are

x = 0, x = - 2, x = 2

2 x^{3} - 3 x^{2} - 14 x + 21 = 0

7 x^{2} + 15 x = 2 x^{3}

x^{4} - x^{3} - 3 x^{2} + 5 x - 2 = 0

x^{3} - 34 x + 12 = 0

r^{3} - 2 r^{2} - 5 r + 6 = 0
