## factoring trinomials when a is greater than 1

Factor out the largest common factor if that a term is not equal to 1 before using FOIL to do the rest. The steps for factoring trinomials, quadratic trinomials, or perfect square trinomials, all with leading coefficients greater than 1 are very similar to how we factor trinomials with a leading coefficient of 1, but with one additional step. It just takes more attention to factor the expression. Suppose (2x + 2) and (x + 3) are paired. Suppose the polynomial is 5x 2 + 15x + 125. Suppose the squared term is 2x2. This Math quiz is called 'Algebra Intermediate - Factoring Trinomials [First term is greater than or lesser than 1]' and it has been written by teachers to help you if you are studying the subject at middle school. Sometimes, the leading coefficient of a quadratic equation may be greater than 1. Learn more about how we are assisting thousands of students each academic year. Get access to hundreds of video examples and practice problems with your subscription! For example, (2x + 1) and (x + 6) can be paired, or (2x + 6) and (x +1). Confused already because you aren't sure what a lead coefficient greater than 1 means?" The expression (2x + 3)(x + 5) is equal to 2x2 + 13x + 15. If (2x + 6) and (x + 1) are paired, then 2x +6x equal 8x, which is also too high. Notice: the steps were exactly the same no matter if a is equal to 1 or greater than 1! Factoring is the reverse of multiplying. Now we will take a look at one more example.
