Equation
1/x+1/(x-2) = 1/4

  1. an equation Left side of the equation is equal to a sum that comprises 2 terms. The 1st 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 x. 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 containing 2 terms. The 1st term of the sum is equal to x. The 2nd term of the sum is negative two Right side of the equation is equal to a rational expression: the numerator of the rational expression is one. The denominator of the rational expression is four.
  2. one divided by x plus one over x plus negative two is equal to one divided by four.
