document.write( "1) Set denominator equal to 0, and determine values for x
\n" );
document.write( "2) Values of x will NOT BE PART of the solution set for x, as they will make the expression undefined
\n" );
document.write( "3) You should get values that make the expression undefined as: \"highlight_green%28system%28x+=+-+6%2Cx+=+-+3%29%29\" \r
