Quita los paréntesis extra.

M = (1 + x)(1 + x2)−1m = 1 + x⁢1 + x2 - 1

Expande(1 + x)(1 + x2)1 + x⁢1 + x2

m = 1 + x2 + x + x3−1m = 1 + x2 + x + x3 - 1

Resta11de11para obtener00.

M = x2 + x + x3 + 0m = x2 + x + x3 + 0

Sumax2x2y00rx2x2.

M = x2 + x + x3m = x2 + x + x3

m = x2 + x3 + xm = x2 + x3 + x

x2x2yx3x3.

M = x3 + x2 + x.
