WILL MARK BRAINLIEST An expression is shown below: 3pf2 − 21p2f + 6pf − 42p2 Part A: Rewrite the expression by factoring out the greatest common factor. Part B: Factor the entire expression completely. Show the steps of your work.

See Below.

Step-by-step explanation:

We have the expression:

Part A:

Find the GCF. Notice that we have a three in every term and a p in every term. Thus, the GCF will be 3p. Factor:

This is the most we can do.

Part B:

Continuing from where we left off, we can factor the entire expression by grouping:

step-by-step explanation:

d

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.
