R0907 a.s. http://faculty.valencia.cc.fl.us/ashaw INTERMEDIATE ALGEBRA GPS # 20 5.4 FACTORING TRINOMIALS NAME: Useful Guidelines: To factor 2 ax bx c + + : Step 1: Find pair whose product is 2 ax . For example: 2 3 7 2 (3 ...)( ...) x x x x + + = + + Step 2: Find pair whose product is c . For example: 2 3 7 2 (3 2)( 1) x x x x + + = + + ? or 2 3 7 2 (3 1)( 2) x x x x + + = + + ? Step 3: Check which one will produce the middle term bx . That’s the right factoring.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
