3 x^{3} + 9 x^{2} - 210 x = 0

x = 0, x = 7, x = - 10

Solution steps

3 x^{3} + 9 x^{2} - 210 x = 0

Factor

3 x^{3} + 9 x^{2} - 210 x : 3 x (x - 7) (x + 10)

3 x (x - 7) (x + 10) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x = 0 or x - 7 = 0 or x + 10 = 0

Solve

x - 7 = 0 : x = 7

Solve

x + 10 = 0 : x = - 10

The solutions are

x = 0, x = 7, x = - 10

(- x - 3)^{3} = 0

6 = \frac{4}{3} y^{34} y

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

n - 70 = 200 - (15 x^{4})

x, x^{3} - y^{3} = 8
