ANSWER
6.63
Explanation:
Equation used: c2 = a2 + b2 ( rearranged due to having the two sides )
c2 = 12^2 + 10^2
c2 = 144 - 100
c2 = 44
c2 = 6.63 ( the square root of 44 )
47 -14i
You can work this out in the straight-forward way, or you can recognize that (6-i) is a common factor. In the latter case, you have ...
... = (6-i)(5 + 3-i)
... = (6 -i)(8 -i)
This product of binomials is found in the usual way. Each term of one factor is multiplied by each term of the other factor and the results summed. Of course, i = √-1, so i² = -1.
... = 6·8 -6i -8i +i²
... = 48 -14i -1
... =
