(2-5i)(6+7i)
To multiply we just use FOIL. But first I like to change any subtractions into additions:
(2+(-5i))(6+7i)
Now we'll multiply:
2*6+2*7i+(-5i)*6+(-5i)*7i
which simplifies as follows:
12%2B14i%2B%28-30i%29%2B%28-35i%5E2%29
Since i%5E2+=+-1:
12+14i+(-30i)+(-35)(-1)
12+14i+(-30i)+35
Adding like terms:
47+(-16i)
