\n" ); document.write( "\"v%28t%29=61-0.61t%5E2\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"v%28t%29=-0.61t%5E2%2B61\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"v%28t%29=-0.61%28t%5E2-100%29\" Divide both terms (-0.61t^2 and 61) by -0.61 to factor it out\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Optionally you can use the difference of squares rule to go from \"t%5E2-100\" to \"%28t-10%29%28t%2B10%29\". So \"v%28t%29=-0.61%28t%5E2-100%29\" is the same as \"v%28t%29=-0.61%28t-10%29%28t%2B10%29\"
