Question: Simplify 2011!+2012!2011!+2010!.
We can factor stuff out from the numerator and denominator.
Let's factor out 2010 from both the numerator and denominator.
The numerator will become 2010(2011+2011×2012).
The denominator will become 2010(2011+1).
In fraction form, this looks like 2010(2011+2011×2012)2010(2011+1)
From there, cancel out 2010, and solve.
You are very welcome!
