m^{3} - 4 m = 0

m = 0, m = - 2, m = 2

Solution steps

m^{3} - 4 m = 0

Factor

m^{3} - 4 m : m (m + 2) (m - 2)

m (m + 2) (m - 2) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

m = 0 or m + 2 = 0 or m - 2 = 0

Solve

m + 2 = 0 : m = - 2

Solve

m - 2 = 0 : m = 2

The solutions are

m = 0, m = - 2, m = 2

3 x^{4} = 27 x^{2}

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

2 (x + 1) - 6 x = 15 x^{21}

x, t = 64 - 6 x^{3}

4 a^{4} + 56 a^{3} + 196 a^{2} = 0
