\n" );
document.write( "would this be a quadratic function problem or would this be like solving a normal equation?
\n" );
document.write( "If i solve it like a normal equation i keep on getting a negative under the square root sign.
\n" );
document.write( "how would i write the answer?
\n" );
document.write( "square root of -81 or square root -27 or square root +/- 27 or 81 or with the -81i \n" );
