You can put this solution on YOUR website!
$\"d+=+sqrt%28-144+%2B+16a%5E2%29\"$
\n" ); document.write( "a > 3, to prevent having the square root of a negative number.
\n" ); document.write( ":
\n" ); document.write( "Assume they want you to solve for a
\n" ); document.write( "square both sides and write it like this
\n" ); document.write( "-144 + 16a^2 = d^2
\n" ); document.write( "16a^2 = d^2 + 144
\n" ); document.write( ":
\n" ); document.write( "Divide both sides by 16
\n" ); document.write( "a^2 = $\"%28%28d%5E2%2B144%29%29%2F16\"$
\n" ); document.write( ":
\n" ); document.write( "Square both sides and you have
\n" ); document.write( "a = $\"sqrt%28%28%28d%5E2%2B144%29%29%2F16%29\"$
\n" ); document.write( ":
\n" ); document.write( "Extract the square root of 1/16
\n" ); document.write( "a = $\"1%2F4\"$ * $\"sqrt%28d%5E2%2B144%29\"$ \n" ); document.write( "

\n" );
