Answer: (6x-5)(2x+3)
Step-by-step explanation:
6 and 2 are factors of 12
5and 3 are factors of 15
Answer:
(6x - 5)(2x + 3).
Step-by-step explanation:
12x^2+8x-15
We use the 'ac' method:
12 * -15 = -180. We need two numbers whose product is -180 and whose sum is +8 ( to make the + 8x).
These are + 18 and - 10 so we have:
12x^2 + 18x - 10x - 15 Now factor by grouping:
= 6x(2x + 3) - 5(2x + 3) (2x + 3) is common to the 2 parts so:
= (6x - 5)(2x + 3).
