This is just an expression. All you can do with an expression is simplify it.

\n" ); document.write( "The best I can tell is that this expression is from the Quadratic Formula. If so, then the entire first part of the expression is divided by 4:
\n" ); document.write( " $\"%281+%2B+sqrt%281+-+4%282%29%28-e%5E7%29%29%29%2F4\"$

\n" ); document.write( "To simplify this, we can start by multiplying the 4 and the 2 inside the square root:
\n" ); document.write( " $\"%281+%2B+sqrt%281+-+8%28-e%5E7%29%29%29%2F4\"$
\n" ); document.write( "and the minus in front of the 8 and the minus in front of the \"e\" cancle each other out:
\n" ); document.write( " $\"%281+%2B+sqrt%281+%2B+8e%5E7%29%29%2F4\"$
\n" ); document.write( "This is as far as you can go without a calculator. And once you start using a calculator you are then dealing with a decimal approximation for the value of the expression.

\n" ); document.write( "\"e\" is a special, named number like $\"pi\"$ . If you calculator does not have a key for \"e\", then use 2.7182818284590451 (or some rounded of version of this) for \"e\". \n" ); document.write( "

\n" );
