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

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

Solution steps

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

Factor

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

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

m - 2 = 0 : m = 2

Solve

m + 1 = 0 : m = - 1

Solve

m - 1 = 0 : m = 1

The solutions are

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

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

1 + 2 x - 3 x^{2} + x^{3} = 2 x - 3

x^{3} - 3 x^{2} + 3 x - 1 = 0

x^{3} - 4 x^{2} - 4 x + 16 = 0

(x^{2} - 64)^{2} + (x^{2} + 5 x - 104)^{2} = 0
