document.write( "Question 425015: I am having a hard time trying to factor a few binomials. Would you mind helping me out? Ok good. Here is one trinomial that I cann't factor. a^2 -5a -20. Another one is a^2 +12ab+27b^2. And the last one is x^2 -8x +15. I think the last one maybe prime, but again I am not sure. \n" ); document.write( "
