For this case we have the following expression:

We must find a term that is a common factor for both terms of the given binomial.
We then have that for 4x, the factored expression is given by:

Answer:
The factored form of given expression is:

Option 2
D
there is always a 1 infront of a variable but since x2 has the largest degree it gives it priority over the others so what ever numbe in front of it is the leading coefficient
The quotient to p/q = -3 is 4
Answer: 
Step by step:

(Used a table of common angles)
C and D is true and others are false
