Then the next step shows this:

-15 - 20i
5
5 - 10i
1 + 2i

multiply top and bottom by complex conjugate of the denominator to "realise" [make real] the denominator. [hint: remember rationalising?...similar to that]
the complext conjugate of any complext no. z = x + iy is x - iy

So:

5 - 10i x 1 - 2i
1 + 2i .... 1- 2i

= (5 - 10i)(1 - 2i)
1^2 - (2i)^2

[diff of 2 squares for denom.]

= -15 - 20i
1 + 4

=-15 - 20i
5

NOTE: i^2 = -1

@thaoroxy2001: there are 3 types of cruel pple. I'm going to write them down in order of dangerousness and cruelness [from lowest to greatest]:

1: pple who think they are cruel...but r just silly, confused lil monkeys.
2. pple who know they are cruel, they are cruel, and they act cruel. There's nothing special about them.
3. Most dangerous group: cruels who pretend to be nice but cruel as hell in nature. they do all these cruel things and pretend nothing happened......U R ONE OF THEM........
