whew!
1) a2-9 = (a-3)(a+3)
2) 4a2-4a+1 = (2a-1)(2a-1)
3) y2+16y+64 = (y+8)(y+8)
4) 81r2 -36rs +4s2 = (9r-2s)(9r-2s)
5) x2 +3x+2 = (x+2)(x+1)
6) x2+8x+12 = (x+6)(x+2)
7) 72 - 22x+x2 = rewrite this as
x%5E2-22x%2B72 = (x-18)(x-4)
8) x2 +x-6 = (x-3)(x+2)
9) x2-5x-24 = (x-8)(x+3)
10) 3x2+11x+10 (3x+5)(x+2)
