Multiplying complex numbers

Question

Multiply 

 

(-1+2i)(-5+3i) 

 

Write answer as a complex number in standard form 

Answer 1

DON'T HOLD BACK WITH TREPIDATION.  Just do the regular "FOIL" process. Remember that i squared is -1; you combine the two Real parts and the two pure imaginary parts to come up with a complex number in the form a + ib.
