1. when trying to determine a strategy for factoring trinomials of the form ax + bx + c,a 1, the binomial factors (mx+p) and (nx + q) were multiplied to give mnx+(mq+np)x + pq. Match each expression to the appropriate section of the algebra tile array shown. Explain your choices. mn mq np pq 0 mx+p nx+q 3 2 6 Lesson 5.3: Factoring Trinomials 3. Mariah tried to factor 3x + 23x-36. Her work is shown. Workbook 5A The value of ac is -108 and the value of b is 23. Two numbers that add to give 23 and multiply to give -108 are 27 and -4. This means the factors of 3x + 23x - 36 are (x+27)(x-4). Comment on Mariah's strategy. If she made an error, make the necessary corrections. ADLC Mathematics 10C 25 25
