Command

Simplify

Expression
(4*x^2-4*x*y)/(x^2-y^2)

  1. A rational expression: the numerator of the rational expression is a sum that contains 2 terms. The first term of the sum is equal to a product of 2 factors. The first factor of the product is four. The second factor of the product is equal to a power. The base is x. The exponent is two. The second term of the sum is equal to a negative product of 3 factors. The first factor of the product is four. The second factor of the product is equal to x. The third factor of the product is equal to y. The denominator of the rational expression is a sum comprising 2 terms. The first term of the sum is a power. The base is x. The exponent is two. The second term of the sum is equal to a negative power. The base is y. The exponent is two.
  2. four multiplied by x exponentiated by two plus negative four multiplied by x multiplied by y over x raised to the power of two plus negative y raised to the power two;
Result
4*x/(y+x)
