Question

I have a question about simplifying a square root...I'll upload a picture of it.

Answer 1

\[\LARGE \frac{12\pm i\sqrt4}{2}\]

??

Answer 2

yes, how do you simplify it?

Answer 3

I worked out the whole problem - just stuck on this last step

Answer 4

well first of all we can get rid of square root
\[\LARGE 4=2^2\]
so
\[\LARGE \sqrt4=\sqrt{2^2}=2\]
and we have:
\[\LARGE \frac{12\pm i2}{2}=\frac{2(6\pm i)}{2}=\]
\[\LARGE \frac{\cancel2(6\pm i)}{\cancel 2}=?\]

Answer 5

6\[6pmi\]

Answer 6

whoops that didn't work.

Answer 7

it would be 6-i and 6+i

Answer 8

\[\LARGE 6\pm i\] use \pm ;)

Answer 9

thanks so much!!
