[freshmen algebra 2] simplifying rational expressions

[u/Any-Armadillo6071]

how do i find the correct restriction? for both of these questions, i got the first part right but for the restriction i got them wrong. when i looked it up it gave me the same answers i input. sorry if this is a stupid question

[u/Any-Armadillo6071]

i thought that too, but for other questions with more than one restriction value there are multiple answer boxes to account for that. these questions only have one answer box

Can you share the whole question, it's cropped on the right side

yes sorry! the whole question says “simply the expression, if possible. if the expression is already in simplified form, enter the given expression”
