*I don't get this one.PLease help me....

Try to factor wherever you can to simplify.

(6 - y)/(y^2 - 2y - 24)

y^2 - 2y - 24 factors are: (y - 6)(y + 4)

Factor out -1 in the numerator: -1(y - 6)

Now we can simplify this fraction:
-1(y - 6)/(y - 6)(y + 4)

Cancel out y - 6 from both the numerator (top) and denominator (bottom).

Now we are left with this:
-1/(y + 4)

And that's as far as we can go to simplify here!

    6-y --------- y^2-27-24 well it should simplify to (6-y)/(y^-1) which then changes to y(6-y) which then equals y(6-y)=0 then you set both parts equal to zero and solve for xero y=0 and/or (6-y)=0 so y=0 or y=6 Did you mean for this …
