I'm attempting to factor the equation -6x^2-12x+48 into the (x-a)(x-b) format. I managed to find that the two factors that would work would be -24 and 12, as multipled together they equal the product of -6 and 48 while when added together equal -12.
So I tried the box method to attempt to figure out the rest of the values
Code: Select all
-6x -24 -6x (-6x^2) (-24x) 12 (12x) (48)
