15t^2-29t-14\ 3t-7 \r
\n" ); document.write( "\n" ); document.write( "Factor to get:\r
\n" ); document.write( "\n" ); document.write( "(3t-7)(5t+2)/(3t-7)\r
\n" ); document.write( "\n" ); document.write( "= 5t+2
\n" ); document.write( "-------------
\n" ); document.write( "Proof:
\n" ); document.write( "(3t-7)(5t+2)
\n" ); document.write( "Use FOIL:
\n" ); document.write( "F: 3t*5t = 15t^2
\n" ); document.write( "O: 3t*2 = 6t
\n" ); document.write( "I: -7*5t = -35t
\n" ); document.write( "L: -7*2 = -14
\n" ); document.write( "------------------
\n" ); document.write( "Combine to get:
\n" ); document.write( "15t^2 -29t - 14
\n" ); document.write( "===================
\n" ); document.write( "So the -29t comes from combining the Outer and the Inner products.
\n" ); document.write( "====================
