Hi, newbie here. I have never been one to often ask for help, but I have a major deadline coming up, and a lot of questions I just can't figure out! Any help would be greatly appreciated.
The first of my problems are as follows.
Simplify:
40. (x+4)(x+1)
41. (2y-7)(4y+4)
42. (4^2+2y^2)(2x^2-y^2)
43. (z+2)^2
44. (2m-3n)(2m+3n)
45. (x+3)(x^2-2x+4)
^ indicates power. I have literally stared at these problems for hours, and even run them through a couple of different solving programs, but the answers keep coming back the same as the question. So what I'm asking is, can these be simplified, and if yes, how?
EDIT
Also, how do I simplify 5hk^2(2h^2k-hk^3+4h^2k^2) ?
