Question

What is the conjugate of the complex number -9 + 5i?

Answer 1

`-9-5i`

Explanation:

When you have a complex number in the form `a+bi`, its conjugate can be found by reversing the sign on the imaginary portion of the number, yielding the complex conjugate `a-bi`.

So, for the complex number `-9+5i`, the `+5i` is the imaginary part. In the complex conjugate, its sign will be `-` instead of `+`, so the complex conjugate of `-9+5i` is

`-9-5i`
