x^{4} + 2 x^{3} - 7 x^{2} - 8 x + 12 = 0

x = 1, x = - 3, x = - 2, x = 2

Solution steps

x^{4} + 2 x^{3} - 7 x^{2} - 8 x + 12 = 0

Factor

x^{4} + 2 x^{3} - 7 x^{2} - 8 x + 12 : (x - 1) (x + 3) (x + 2) (x - 2)

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

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

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

Solve

x - 1 = 0 : x = 1

Solve

x + 3 = 0 : x = - 3

Solve

x + 2 = 0 : x = - 2

Solve

x - 2 = 0 : x = 2

The solutions are

x = 1, x = - 3, x = - 2, x = 2

x \cdot (x^{2} - 6) - 1 \cdot (x - 6) = 0

x^{5} - 12 x^{3} + 24 = 0

a^{2} - a^{3} = 100

m^{4} - 2 m^{3} + 7 m^{2} - 5 m = 0

x^{3} - 6 x^{2} + 3 x - 6 = 0
