xy - 3x - 8y + 24

(3x-y)-(8y+24)

8y+24

4x^2 + 20x + 5y +xy

36x+(5y+x)

36x-5y

I don't think so it's right.Your question xy-3x-8y+24 is itself the answer.It cannot be further calculated bcause it doesn't have the terms containing the same variables.

If you are factoring then no. Using the commutative and associative properties I can rewrite the equation:

xy - 3x - 8y +24

xy -8y -3x +24

y(x-8) -3(x-8) -factor by grouping

(x-8)(y-3) factor out the (x-8)

Sorry forgot to answer the second one for you. You use the same techniques.

4x^2+20x+5y+xy

4x^2+20x+xy+5y

4x(x+5)+y(x+y)

(x+5)(4x+y)
