Is this multiple choice?

OpenStudy (anonymous):

Remember that the conjugate is when you change the sign between the two numbers. The conjugate of 2i-2 is 2i+2. Does that help?

OpenStudy (anonymous):

yes i think B

OpenStudy (anonymous):

2 − 4i 2 + 4i 4i + 2 4i − 2

If you are finding the conjugate of 2-4i, then the correct answer is B! Good job :)

OpenStudy (anonymous):

2-4i is A ?

OpenStudy (anonymous):

The original problem was 2-4i? Correct?

OpenStudy (anonymous):

The CONJUGATE of 2-4i is B :)
