21x^2 -5x-6 how would i go about factoring this expression?
\n" ); document.write( ":
\n" ); document.write( "You just have to play around with the factors of 21 & 6
\n" ); document.write( "21: 3 & 7
\n" ); document.write( "6: 3 & 2
\n" ); document.write( "multiply factors
\n" ); document.write( "3 * 3 = 9
\n" ); document.write( "2 * 7 = 14
\n" ); document.write( "now give them the signs and position to equal -5
\n" ); document.write( "-14 + 9 = - 5
\n" ); document.write( "(3x - 2)(7x + 3), check is by FOILing
\n" ); document.write( "
\n" ); document.write( "
\n" );
