\n" ); document.write( " it (9), and added it to both sides of the equation \r
\n" ); document.write( "\n" ); document.write( "This is where I get stuck. I'm supposed to write the left side in squared form, but because there is a plus and minus, it wouldn't be just one factor squared. Would I write this as (x-3)(x+3)? If so, how would I take the square root of that? \r

(x - 3)^2 = 6\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x - 3 = ± sqrt(6)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 3 ± sqrt(6)
\n" ); document.write( "
\n" );
