Need asap. choose the expression that represents a cubic expression.

2x + 11
−3x2 − 2x + 11
4x3 − 3x2 − 2x + 11
5x4 + 4x3 − 3x2 − 2x + 11

The answer is  C 4×3 - 3×2 -2x + 11

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.
