How to simplify fractions?
I have the following expression (−1)n−2n−14(2n+1) It clearly equals (−1)n4(2n+1)−14.
Is there anyway to make sage show this?

expand the expression and then simplify partially (like transforming by hand)
var('n')
expr = ((-1)^n - 2*n -1) / (4*(2*n + 1))
show(expr)
expr2 = expr.expand()
show(expr2)
expr2.op[0] + sum(expr2.op[1:]).simplify_full()
Use bool() like so
,var n
f1=((-1)^n-2*n-1)/4/(2*n+1)
f2=(-1)^n/4/(2*n+1)-1/4
show(f1==f2)
bool(f1==f2)Your Answer
