Factor Completely

On page 58 there is a big box that Sullivan calls Mixed Practice. I will spend several days inside this box reviewing factor completely. On that same page,  there is another series of factoring problems under the name Applications and Extensions.

For Applications and Extensions, there is a TRIANGLE FIGURE with an integral symbol in the middle. By this, Sullivan means that the next set of questions are often found in calculus. So, in short, I will be on page 58 for several days before moving on to Section R.6 or Synthetic Division. I will only select problems that I haven't factored completely in many years or that I simply like.

Page 58;  problems 84.

Factor the polynomial completely.  If the polynomial cannot be factored, say it is prime.

3x^2 - 12x + 15

Factor out GCF.

Our GCF = 3

3(x^2 - 4x + 5)

You say?
