You can put this solution on YOUR website!
To solve this you use the FOIL method;
\n" ); document.write( "F=first
\n" ); document.write( "O=outside
\n" ); document.write( "I=inside
\n" ); document.write( "L=last
\n" ); document.write( "(x-9)(x-11)
\n" ); document.write( "Multiply first terms in each set of parethesis;
\n" ); document.write( "x(x)= $\"x%5E2\"$
\n" ); document.write( "Multiply outside;
\n" ); document.write( "x(11)=11x
\n" ); document.write( "multiply inside;
\n" ); document.write( "9(x)=9x
\n" ); document.write( "multiply last;
\n" ); document.write( "9(11)=99
\n" ); document.write( "So you have;
\n" ); document.write( " $\"x%5E2\"$ -11x-9x+99
\n" ); document.write( "Add like terms;
\n" ); document.write( " $\"x%5E2\"$ -20x+99
\n" ); document.write( "Hope you understand;
\n" ); document.write( "=) \n" ); document.write( "

\n" );
