Factoring Trinomials When the Leading Coefficient is not 1. Here are the steps required for factoring a trinomial when the leading coefficient is not 1: Step 1: Make sure that the trinomial is written in the correct order; the trinomial must be written in descending order from highest power to lowest power… If the remaining trinomial is still of the form ax2 + bx + c, find two integers, r and s, whose sum is b and whose product is ac. 1 decade ago. The following diagrams show how to factor trinomials where the leading coefficient is 1 (a = 1). factoring trinomials a is greater than 1. Since 1 and 4 add up to 5 and multiply together to get 4, we can factor it like: (x+1) (x+4) If you had trouble, you may want to go back and Factoring when the coefficient of x 2 is greater than 1. This means that I'll want to use the pair 3 and 4. check out the factoring by grouping lesson as that is a prerequisite to this lesson.
