roots

x^{3} + 2 x^{2} - 16 x - 32

x = - 2, x = - 4, x = 4

Solution steps

x^{3} + 2 x^{2} - 16 x - 32

The roots are the intercepts with the x-axis

(y = 0)

x^{3} + 2 x^{2} - 16 x - 32 = 0

Factor

x^{3} + 2 x^{2} - 16 x - 32 : (x + 2) (x + 4) (x - 4)

(x + 2) (x + 4) (x - 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 2 = 0 or x + 4 = 0 or x - 4 = 0

Solve

x + 2 = 0 : x = - 2

Solve

x + 4 = 0 : x = - 4

Solve

x - 4 = 0 : x = 4

The solutions are

x = - 2, x = - 4, x = 4

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

(x + 4) (x^{2} - x + 3) = 0

(x^{2} - 2 x) (4 - x) = 0

x^{4} - x^{3} - 27 x + 27

6 x^{4} + 8 x^{3} = 0
