<span> (5+2i) * (5+2i) 

Distribute...

25 + 10 i + 10 i  + 4i^2 

Remember ... when there is a number with i^2 it will equal to (-1)...

So that means in this question .. I replace  4i^2 with - 4 because 4 ( -1) = -4 

Now I can combine like terms....

25 + 10i + 10i - 4 

Soo... The answer is 21 + 20i</span>
