Expression

3/(x-2)-6/(x^2-4)/(3/(x+2)+1/(x+2))

  1. A sum comprising 2 terms. The 1st term of the sum is equal to a fraction: the top of the fraction is three. The bottom of the fraction is a sum that consists of 2 terms. The 1st term of the sum is equal to x. The 2nd term of the sum is equal to negative two. The 2nd term of the sum is a negative fraction: the numerator of the fraction is a quotient: dividend of the quotient is six. Divisor of the quotient is a sum that contains 2 terms. The 1st term of the sum is equal to a power. The base is x. The exponent is two. The 2nd term of the sum is equal to negative four. The denominator of the fraction is a sum containing 2 terms. The 1st term of the sum is a rational expression: the numerator of the rational expression is three. The denominator of the rational expression is a sum that consists of 2 terms. The 1st term of the sum is equal to x. The 2nd term of the sum is equal to two. The 2nd term of the sum is equal to a rational expression: the numerator of the rational expression is one. The denominator of the rational expression is a sum of 2 terms. The 1st term of the sum is equal to x. The 2nd term of the sum is two.
  2. three divided by x plus negative two plus negative six divided by x to the power of two plus negative four over three over x plus two plus one over x plus two;
