When x2 + 3x – 4 is subtracted from x(x2 + 3x – 2), the difference is: A. x3 + 2x2 – 5x + 4
B. x3 + 2x2 + x - 4
C. -X3 – 2x2 + 5x + 4
D. -x3 + 4x2 + x - 4

this was already solved by me with a different person. if you look it up in the search bar at the top of the page, you will get the 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.

1=b 2=c 16=c can i get brainliest
