Could someone solve this for me and show steps? :
Problem: The product of z and the complex number 5 - 6i is a real number. Find 2 possible nonzero vaules of z.
I can think of the first one off the top of my head, 5+6i This is because of difference of squares formula, (a+b)(a-b)=a^2-b^2 hope this helps a bit even if i didnt solve the whole thing
