4 m^{3} - 40 m^{2} + 36 m = 0

m = 0, m = 1, m = 9

Solution steps

4 m^{3} - 40 m^{2} + 36 m = 0

Factor

4 m^{3} - 40 m^{2} + 36 m : 4 m (m - 1) (m - 9)

4 m (m - 1) (m - 9) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

m = 0 or m - 1 = 0 or m - 9 = 0

Solve

m - 1 = 0 : m = 1

Solve

m - 9 = 0 : m = 9

The solutions are

m = 0, m = 1, m = 9

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

x^{3} - 14 x^{2} + 49 x - 36 = 0

(x + 1) (x + 2) (x + 3) + 5 = 0

x^{5} + x^{2} - 1 = 0

x, 0.1 x^{3} + 8.1 x - 64 = 0
