:: Factorising ::

I need to factorise this equation and i`ve tried but really can't find the answer!
10n - 20N + 10
Help?
thanks.

Re: :: Factorising ::

First, take out the common multiple of 10.

10(n² - 2n + 1)

The bit in the brackets now factorises easily, to give:

10(n-1)²


Why did the vector cross the road?
It wanted to be normal.
