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. 34. -102x^3y 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. 34. 15xy^3+y^4 38. 3m^2-5m^2p+3p^2-5p^3 I really need to do this since I really need to get my grade up in this class. Thanks in advance.
