then factor. by grouping. so, (Finding p and q is not always easy. Just list all the ways to factor (ac) and add up each pair. Be careful of your signs. If none of the pairs add up to the right number then the trinomial is simply not factorable, (or you left off a pair).)

Factor : 8x2+40x +18. Steps for Factoring using the Cross Method. If the Trinomial has a Greatest Common Factor (GCF) factor it out. 2(4x2+20x+9) Determine factors of the 1st term (in trinomial) 2x and 2x or 4x and 1x. Determine factors of the last term (in trinomial) 3 and 3 or 9 and 1. Arrange the factor combinations vertically

Step 1: factor out the greatest common factor, GCF – if there is one – and write it as a factor times the remaining trinomial. In the example GCF = 2 and the problem becomes: ( 2 )( 4x2 + 11x + 6 ) Note that a, b, and c are still integers, but a is now 4, b has become 11, and c is now 6.

How to Factor Using the Reverse Distributive Method. The premise of this method is to create a factor by grouping scenario so that students can write the trinomial in an equivalent product of binomials. To do this we need to know how to split the middle term into to two terms as in the previous examples 4th and 3rd line respectively.

Factor trinomial in Step #2. DIVIDE. the last term in each binomial with the dropped coefficient. Reduce the fractions, if possible. For fractions that remain, “SLIDE ” the denominator in front of the first term in the binomial. The trinomial is now factored. Answer: Try These: 1. 3x2 + 13x – 10

Simple Trinomial. Complex Trinomial. 1) Common Factor - find the largest number and variable combination that go into each term - divide each term by the common factor. Ex. Factor 6x3 – 12x2 + 24x. Solution: = _____ 2) Difference of Squares - look for a2 – b2 , since the two factors are (a + b) and (a – b) Ex. Factor 36x2 –49y2
