Question 999615
.
1.  Factor  {{{h^2 - 9hs + 9s^2}}}.


      Hello, I suspect that there is a typo/mistake in your writing.
      It should be  {{{h^2 - 6hs + 9s^2}}}.


      If so,  then  {{{h^2 - 6hs + 9s^2}}} = {{{(h-3s)^2}}}.


      Otherwise,  it doesn't make sense.  Please let me know by sending you response in the section  "Comments from student". 

      Do not forget to include the number of the problem  (# 999615)  in your comment in order I could identify it.



2.  Factor  {{{-a^3 - 2a^2 - a}}}.


      {{{-a^3 - 2a^2 - a}}} = {{{(-a)*(a^2 + 2a +1)}}} = {{{(-a)*(a+1)^2}}}.



3.  Factor  {{{8x^2 - 10x - 3}}}.


      {{{8x^2 - 10x - 3}}} = (2x-3)*(4x+1).
