The given expression is: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y = $\"x%5E2+%2B+7x+-+18+\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "By the method of factoring: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x%5E2+%2B+9x+-+2x+-+18\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x(x + 9) - 2(x + 9)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "==> (x + 9)(x - 2) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Thus the solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence the solution set is: (-9,2) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "That is option (d) is the right answer.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "regs\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "

\n" );
