Hi.\r
\n" ); document.write( "\n" ); document.write( "To solve the polynomial compare it with ax^2 + b x + c \r
\n" ); document.write( "\n" ); document.write( "We get a = 1, b = -2, c = -63\r
\n" ); document.write( "\n" ); document.write( "Sum = b = -2
\n" ); document.write( "Product = a * c = 1 * -63 = -63\r
\n" ); document.write( "\n" ); document.write( "Now we have to find two numbers such that there product is -63 and their sum is -2\r
\n" ); document.write( "\n" ); document.write( "Can you find the same?\r
\n" ); document.write( "\n" ); document.write( "Yes --- -63 can be broken up into two parts -9 and +7
\n" ); document.write( "The product of the numbers -9 and 7 is -63 and the sum is -2\r
\n" ); document.write( "\n" ); document.write( "So we get\r
\n" ); document.write( "\n" ); document.write( " m^2 - 2m - 63
\n" ); document.write( " m^2 - 9m + 7m - 63
\n" ); document.write( " m (m - 9) + 7(m - 9) We have taken m common from first two terms and
\n" ); document.write( " 7 common from the last two terms\r
\n" ); document.write( "\n" ); document.write( " (m - 9) (m +7) (By taking out (m-9) common\r
\n" ); document.write( "\n" ); document.write( "These are the required factors.\r
