Question
Solution 1
To multiply complex numbers, you can use the distributive property, just like you would with real numbers. Here's how you can do it:
Step 1: Distribute each part of the first complex number to each part of the second complex number.
(3 - 5i)(5 - 7i) = 35 + 3(-7i) - 5i5 - 5i(-7i)
