Chapter 6 - Section 6.3 - Factoring Trinomials of the Form ax2+bx+c - Practice: 2

Answer

2x²-11x+12= (2x-3)(x-4) 6x²-5x+1= (3x-1)(2x-1)

Work Step by Step

We know that the second factors must both be negative because the c value is positive and the b value is negative. This leaves (2x-3)(x-4) because after the -4 is multiplied with the 2x and -3 with the x, then summed. It adds to -11, the b value. The same is true for the second problem.
