Question: How to Perform a Basic Simplification

I would like to have Maple reproduce the well known result that the geometric power series with first term 1 and common ratio x, with |x|<1, converges to 1/(1-x). When I do:

 

sum(x^k,k=0..infinity);

 

I get - 1/(x-1). Which is okay, but is there a way to force Maple to produce 1/(1-x)?

 

Thanks!
