x^2 +4kx -k = 0
\n" ); document.write( "x^2 +4kx = k
\n" ); document.write( "x^2 +4kx +4k^2 = k +4k^2
\n" ); document.write( "(x +2k)^2 = k +4k^2
\n" ); document.write( "x+2k = sqrt(k+4k^2)
\n" ); document.write( "x+2k = sqrt(k(1+4k))
\n" ); document.write( "x+2k = sqrt(k) * sqrt(1+4k)
\n" ); document.write( "x = sqrt(k) * sqrt(1+4k) - 2k
\n" ); document.write( "
