Take 1/2 of the coefficient of the $\"x\"$ term,
\n" ); document.write( "then square it, then add it to both sides
\n" ); document.write( " $\"+x%5E2+%2B+15x+%2B+%2815%2F2%29%5E2+=+5+%2B+%2815%2F2%29%5E2+\"$
\n" ); document.write( " $\"+x%5E2+%2B+15x+%2B+225%2F4+=+20%2F4+%2B+225%2F4+\"$
\n" ); document.write( " $\"+%28+x+%2B+15%2F2+%29%5E2+=+245%2F4+\"$
\n" ); document.write( "Take the square root of both sides
\n" ); document.write( " $\"+x+%2B+15%2F2+=+sqrt%28245%29%2F2+\"$
\n" ); document.write( " $\"+x+=+%28+-15+%2B-+sqrt%28245%29%29+%2F+2+\"$ \n" ); document.write( "
