This week in Pre Calculus, we learned how to factor trinomials.

The first step is to multiply the first term with the third term

The second step, is to find all factors in that product that when you add or subtract = to the second term.

Once that’s done you can rewrite the formula, coming up with two binomials.

If there are any terms you can simplify in the binomials you take them out, and the two binomials should be the same.

The leftovers makes one binomial and the other makes one too.
