Command

Expand

Expression

(1-x^n)*(1-x^2*n)

  1. A product that consists of 2 factors. The first factor of the product is a sum comprising 2 terms. The first term of the sum is one. The second term of the sum is a negative power. The base is x. The exponent is n. The second factor of the product is a sum that contains 2 terms. The first term of the sum is equal to one. The second term of the sum is a negative product comprising 2 factors. The first factor of the product is a power. The base is x. The exponent is two. The second factor of the product is n.
  2. left parenthesis one plus negative x to the power n right parenthesis multiplied by opening brace one plus negative x to the power two multiplied by n closing brace.

Result

n*x^(n+2)-x^n-n*x^2+1
