Section 6.2 Limits of the form zero over zero: Add parentheses to an expression

In the problem where they have to factor the denominator of (x-1)/(x^2 + 2x - 3), the answer x+3 is accepted as correct. But the answer needs to be (x+3), in parentheses. Either put parentheses around the box where students are to type their answer, or require that there be parentheses in the students' answer.
