roots

x^{3} + 2 x^{2} - 11 x - 12

x = - 1, x = 3, x = - 4

Solution steps

x^{3} + 2 x^{2} - 11 x - 12

The roots are the intercepts with the x-axis

(y = 0)

x^{3} + 2 x^{2} - 11 x - 12 = 0

Factor

x^{3} + 2 x^{2} - 11 x - 12 : (x + 1) (x - 3) (x + 4)

(x + 1) (x - 3) (x + 4) = 0

Using the Zero Factor Principle:

ab = 0

then

a = 0

b = 0

x + 1 = 0 or x - 3 = 0 or x + 4 = 0

Solve

x + 1 = 0 : x = - 1

Solve

x - 3 = 0 : x = 3

Solve

x + 4 = 0 : x = - 4

The solutions are

x = - 1, x = 3, x = - 4

- 39 = 1 - 5 x^{9}

x^{5} - 16 x + 9 = 0

x^{3} - 16 x = 0

x^{3} - 14 x - x^{2} + 24 = 0

2 x^{4} - 15 x^{3} + 32 x^{2} - 30 x + 56 = 0
