3x−4+2=8x−1−5? 3x−4+2=8x−1−5 3x+−4+2=8x+−1+−5
(3x)+(−4+2)=(8x)+(−1+−5) (Combine Like Terms)
3x+−2=8x+−6
3x−2=8x−6

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.
