They are often written in the quadratic form as: There will be 4 terms. Include in your solution that the product of two binomials gives back the original trinomial. _____ 1) 2 11 15xx2 2) 3 16 12xx2 3) 3 8 16xx2 4) 2 13 6xx2 direction: Show all your work in the space provided. Grouping steps for factoring “hard” trinomials decide your signs for the parentheses.
