solve this polynomial 3t^2+16t+21
\n" ); document.write( "we need to factor this polynomial
\n" ); document.write( "(3t+7) * (t+3) = 0
\n" ); document.write( "================================
\n" ); document.write( "t+3 = 0
\n" ); document.write( "t = -3
\n" ); document.write( "================================
\n" ); document.write( "3t+7 = 0
\n" ); document.write( "t = -7/3
\n" ); document.write( "======================================
\n" ); document.write( "t = -3 or -7/3
\n" ); document.write( "
