16.  50a^3b - 8ab = 2 * 5 * 5 * a * a * a * b - 2 * 2 * 2 * a * b
                         GCF is 2ab (pull those off each term)
                         2ab (25a^2 - 4)

[tex]16)~50a^3b-8ab=2ab(25a^2-4)=2ab(5a-2)(5a+2)\\\\ 17)~k^2+16k+64=(k+8)^2\\\\ 18)~8m^2-6m-5=(4m-5)(2m+1)\\\\ 19)~n^3+5n^2-9n-45=n^2(n+5)-9(n+5)=(n^2-9)(n+5)=\\\\=(n-3)(n+3)(n+5)[/tex]
