Answer:

-2 - 3i

Explanation:

Given a complex number z = x ± yi then the complex conjugate is

#color(red)(|bar(ul(color(white)(a/a)color(black)(barz=x∓yi)color(white)(a/a)|)))#

Note that the real part remains unchanged, while the 'sign' of the imaginary part is reversed.

Hence the complex conjugate of -2 + 3i is #color(red)(|bar(ul(color(white)(a/a)color(black)(-2-3i)color(white)(a/a)|)))#
