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

m = - 1, m = 2, m = - 3

Solution steps

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

Factor

m^{3} + 2 m^{2} - 5 m - 6 : (m + 1) (m - 2) (m + 3)

(m + 1) (m - 2) (m + 3) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

m + 1 = 0 or m - 2 = 0 or m + 3 = 0

Solve

m + 1 = 0 : m = - 1

Solve

m - 2 = 0 : m = 2

Solve

m + 3 = 0 : m = - 3

The solutions are

m = - 1, m = 2, m = - 3

2 x^{5} + 36 = 2 x - 6

4 x^{4} - 8 x^{2} + 3 = 0

x^{4} = 41

(x^{2} - 1) \cdot (x^{2} - 12) + 24 = 0

x^{10} = 263
