Answer:

(3x-2)(4x-1)

Step-by-step explanation:

1. take the a and the c value and multiply them together to isolate x^2. it should be x^2 -11 +24.

2. find what multiplies to 24 and adds up to -11. its -8 and -3.

3. factor like normal and get (x-8) (x-3)

4. divide the -8 and -3 in the factors by 12 (the original a value)

-8/12 = -2/3 and -3/12 = -1/4.

5. the denominator gets moved to the x value to get (3x-2)(4x-1)
