how do you factor this?

Answer:
Step-by-step explanation:
What two numbers multiply to equal -48, but add to equal -2? The method is multiplying a*c and seeing if they add up to b. Those two numbers are -8 and +6.
[tex]6x^2-2x-8=6x^2-8x+6x-8[/tex]
Now, factor by grouping
[tex](6x^2-8x)+(6x-8)=2x(3x-4)+2(3x-4)\\(2x+2)(3x-4)[/tex]
