I got it wrong and im on my last chance. Please show your work to help me understand! Will mark as BRAINLIEST!!

12x – 3 = 9x +27

=> 12x – 9x = 27 + 3

=> 3x = 30

=> x = 30/ 3

=> x = 10

answer: answer

step-by-step explanation:

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.
