Question 456079: how do you simplify the equation: (r^2 - r - 6)/ (r^2 -r - 12)
also how do you simplify: (-8(4-y))/((y+2)(y-4))

Answer by richwmiller(17219) (Show Source): You can put this solution on YOUR website!
hints:
-(4-y)=y-4
factor r^2-r-6
(r-3)*(r+2)
and factor
r^2-r-12
(r-4)*(r+3)
nothing can be done with the factors
