$\"+x%5E3+%2B+ax+%2B+3a+%2B+3x%5E2+\"$
\n" ); document.write( "factor an x out of the first pair and a 3 out of the second pair
\n" ); document.write( " $\"+x%28x%5E2%2Ba%29+%2B3%28a%2Bx%5E2%29+\"$
\n" ); document.write( "x^2+a is the same thing as a+x^2 ... rewrite it as such
\n" ); document.write( " $\"+x%28x%5E2%2Ba%29+%2B3%28x%5E2%2Ba%29+\"$
\n" ); document.write( "factor out x^2+a
