simplify the expression:
\n" ); document.write( "5x+15 over 3x divided by x+3 over 9x
\n" ); document.write( "-----------------
\n" ); document.write( "Invert the denominator and multiply to get:
\n" ); document.write( "[5x+15]/[3x] * [9x/(x+3)]\r
\n" ); document.write( "\n" ); document.write( "-----------------------
\n" ); document.write( "Factor where you can:\r
\n" ); document.write( "\n" ); document.write( "[5(x+3)]/[3x] * [9x/(x+3)]
\n" ); document.write( "------------
\n" ); document.write( "Cancel factors common to a numerator and a denominator to get
\n" ); document.write( "such as 3, x, (x+3):
\n" ); document.write( "---
\n" ); document.write( "[5/1] / [3/1]
\n" ); document.write( "---
\n" ); document.write( "= 15
\n" ); document.write( "------------------------\r
