Asked by Amy
Hi
Just wandering
When I factorise the following :
4s-16t+20r
It will equal to 2 ( 2s - 8t + 10 r )
This was the answer in the book
However , I managed to factorise it to become :
4 ( s-4t+5r)
is this correct ? Because when you multiple it out , it gives you the same anwer which is 4s-16t-20r
Also , another one was :
56x^2y - 28 xy^2
In the book the anwer gave me : 7xy ( 8x - 4y)
I got 28xy ( 2y - y)
Is this the same ?
If not .. why ?

You are correct on both counts, the book is in error.
