  x = (-3 ± i√31)/8

Step-by-step explanation:

There is nothing to solve. It can be simplified to ...

  x = (-3 ± i√31)/8

  x = (-3/8) +i(√31)/8  or  (-3/8) -i(√31)/8

Factoring -1 from under the radical puts i (the imaginary unit) in front of the radical. A factor of 2 can be removed everywhere.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.
