I'm supposed to get 2 answers. A positive conjugate and a negative conjugate.
However when I solve it, I get an odd fraction and the website keeps telling me that this is a wrong answer. And the formatting is right. So I know I'm doing something wrong.
Could someone tell me how these sort of problems are solved? I know most of the steps, but I'm missing something.
Thanks.
