\n" ); document.write( "= 3t(5t + 3) ______ 4(5t + 3) [I have no idea what to insert]
\n" ); document.write( "
\r\n" );
document.write( "Just insert a negative or minus sign, because you are factoring -4 out\r\n" );
document.write( "of the two terms -20t - 12 getting -4(5t+3).  So that step is simply:\r\n" );
document.write( "\r\n" );
document.write( "3t(5t + 3) - 4(5t + 3)\r\n" );
document.write( "\r\n" );
