Question

What is the product of 5−2i and 3−4i? Enter your answer, in standard form, in the box

Answer 1

Answer:

$\boxed{7-26i}$

Step-by-step explanation:

The binomials are multiplied in the usual way, using FOIL or the distributive property:

  (5 -2i)(3 -4i) = 15 -20i -6i +8i²

Since i² = -1, this becomes ...

  = 15 -20i -6i -8 = 7 -26i
