Help this please do this and do all of this really need help

I think it best to actually do the problem to determine the correct answer.

Clearing out the fractions, I found that

x(x-2) - (x -1) = 2x -5. This results in x=2 and x=3.

However, 2 is not a solution (but is an extraneous solution), because substituting 2 for x in the 2nd term results in div. by zero.

Thus, only the second answer is correct.

Answer:

10 + 5i & 10 - 5i

Step-by-step explanation:

10 + 5i is still just 10 + 5i because we treat i like it's x.

Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?

Hope this helped.
