Sorry to bother you guys but it would be great if you could provide a little help for me on my homework. I knew how to do these things when I was at school but I have had alot of other things on my mind today and I forgot how to do it by the time I got home. So here is a few different types of problems that I couldn't figure out.
Factor each expression completely. Do not use exponents.
Find the GCF of the given monomials.
42. 17a, 34a^2
50. 14a^2b^2, 18ab, 2a^3b^3
Complete. In exercises with two blanks, both blanks represent the same expression.
30. (a^2+3ab)+(2ac+6bc)=a( ? )+2c( ? )
Factor each polynomial.
I really need to do this since I really need to get my grade up in this class.
Thanks in advance.
