7 m^{3} - 14 m^{2} - 168 m = 0

m = 0, m = - 4, m = 6

Solution steps

7 m^{3} - 14 m^{2} - 168 m = 0

Factor

7 m^{3} - 14 m^{2} - 168 m : 7 m (m + 4) (m - 6)

7 m (m + 4) (m - 6) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

m = 0 or m + 4 = 0 or m - 6 = 0

Solve

m + 4 = 0 : m = - 4

Solve

m - 6 = 0 : m = 6

The solutions are

m = 0, m = - 4, m = 6

1920 x^{3} + 3000 x^{2} - 400 = 0

5 = 3 - \frac{2}{7} c^{3} - 72 c, 25 = 2

4 x^{3} + 13 = 45

5 x (x - 1)^{2} = 1

3 x^{4} - 3 x^{3} = 10 x^{2}
