Factor(ise):
\n" ); document.write( " $\"y%5E2-7x%2B10\"$ The factors will be two binomials of the form: (y+m)(y+n) in which m*n = 10 and m+n = -7
\n" ); document.write( "Here are a few possibilities:
\n" ); document.write( "m=2 and n=5...m*n = 10 and m+n = 7 No good 'cause you need m+n = -7
\n" ); document.write( "m = -2 and n = -5 ...m*n = 10 and m+n = -7 Good!, So...
\n" ); document.write( " $\"y%5E2-7x%2B10+=+%28y-2%29%28y-5%29\"$ \n" ); document.write( "

\n" );
