Answer:
A. 
B. 
Step-by-step explanation:
Consider the equation

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.
First, use distributive property:

So, the equation is

This equation has no solutions when

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.
So, the equation

has infinitely many solutions when

In other cases, the equation has a unique solution

Answer:
2x³ + 5x² - 12x
Step-by-step explanation:
The correct answer doesn't seem to be listed...
(fg)(x) = (2x² - 3x)(x + 4)
Which equals...
2x²(x) + 2x²(4) + (-3x)(x) + (-3x)(4)
Which simplifies to...
2x³ + 8x² - 3x² - 12x
2x³ + 5x² - 12x
