Explanation:
Given a complex number
#z=a+-bi# Then the complex conjugate
#barz# is
#color(red)(|bar(ul(color(white)(a/a)color(black)(barz=a∓bi)color(white)(a/a)|)))# Note that the real part , remains unchanged while the
#color(red)"sign"# of the imaginary part reverses.Thus the conjugate is
#-2+sqrt5i#
