> FullSimplify[Expand[x + (x + x^2)^4] > /. x -> y - 1] /. y -> x + 1 A slightly different idea might be to 'remove' a part Here are the 3 problem equations: e1 = Expand[a + (a + b)^4]; e2 = Expand[x + (x + x^2)^4]; e3 = Expand[x + (x + x^2)^ 16]; (* This doesn't do much at all...*) FullSimplify /@ {e1, e2, e3}; (* This helps a little *) FullSimplify[e1 - a] + a a + (a + b)^4 FullSimplify[e2 - x] + x x + x^4*(1 + x)^4 FullSimplify[e3 - x] + x x + x^16*(1 + x)^16 Interesting subject.
