If the reciprocal of (x-2) is (x+2) what is the greatest possible value of x
\n" ); document.write( "Express your answer in simplest radical form
\n" ); document.write( ":
\n" ); document.write( "Let's just solve for x and see what happens
\n" ); document.write( ":
\n" ); document.write( "\"1%2F%28%28x-2%29%29\" = x + 2
\n" ); document.write( "1 = (x+2)(x-2)
\n" ); document.write( "1 = x^2 - 2x + 2x - 4
\n" ); document.write( "1 = x^2 - 4
\n" ); document.write( "0 = x^2 - 4 -1
\n" ); document.write( "0 = x^2 - 5
\n" ); document.write( "Therefore
\n" ); document.write( "x = +/-\"sqrt%285%29\"
\n" ); document.write( "the greatest possible value then: x = \"sqrt%285%29\"
\n" ); document.write( "
\n" ); document.write( "
\n" );
