thanks,can you help me with this one:

xy-3x-8y+24

I know you have to go, but you should be able to figure these out by now. Take out x from the first 2 and 8 from the second 2:
x(y-3)-8(y-3)
(x-8)(y-3)

ac-bc+ad-bd
*I seriously only have 2 more minutes now,I told my mom I needed to write something really quick!!Please help me,you have to factor by group

Take out c from the first 2 and d from the second 2:
c(a-b)+d(a-b)
(c+d)(a-b)
