Question

The sum of two imaginary numbers is -7-6i. If one of the numbers is -12+2i, what is the other imaginary number?​

Answer 1

5-8i

Explanation:

-7-6i and -12+2i

Treat it as a polynomial. We all know that i=square root of -1, but in this case, treat it as a polynomial.

-12+5=-7

2i-8i=6i

So 5-8i
