1. would you factor out the gcf, use the perfect square trinomial pattern, or the difference of squares pattern?
4x^2 - 25
2. show how you would use the approach you picked by factoring this binomial.

Approach: Difference of Squares Pattern

Step-by-step explanation:

The given binomial is:

We can rewrite to obtain:

This is a difference of two squares, so we will factor using difference of squares pattern.

Recall that:

If we let

and

Then we can factor the given binomial to obtain:

on monday rodney ate 1/4th of the sandwich = 3/12

on tuesday he ate 1/3rd of the sandwich = 4/12

therefore in total he has eaten = 3/12 + 4/12 = 7/12

thus we can say that he has eaten 7/12 of the sandwich on monday and tuesday alltogether.
