Consider the expression below. Use it to match the correct response(s) from the left with each item on the right.

Hint: The first step is to factor the denominator: x^2-x = x(x-1)

  • x ≠ -1

  • x ≠ 0

  • x ≠ 1

  • x ≠ 2

  • What is the sum of the two rational expressions in simplest form?

  • Identify any restriction(s) on the variable.
