R.<X>=PolynomialRing(ZZ,'X')
X=R.gen()
P=(X+1)²+1
show(P)The result is X²+2X+2 while i would like sage to show (X+1)²+1.
How can i do that ?
Use symbolic variables ?
sage: X=var('X')
sage: ((X+1)**2+1)
(X + 1)^2 + 1But P[2] (to get the coefficient before X²) doesn't work anymore with var.
Use P.coeffs() to get a list of all of the coefficients.
But looks like sage will still expand e.g. 5(2x -7) into 10*x - 35. How to keep it in the original form?
