You can put this solution on YOUR website!
The given expression is: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x%5E2+-+100\" \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "This is of the form \"a%5E2+-+b%5E2\". The expansion of which is (a + b)(a - b) \r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "So writting the above expression in this form, we get: \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "(x + 10)(x - 10) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, x can take either of the values, that is 10 or -10.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, the solution.
\n" ); document.write( "
\n" );
