Question: Match them whether or not they are identities
My reasoning: My reasoning to figure this out is to simply choose whatever value I'd like for a and b, then plug in it to the equation. The reason I am doing that is because "An identity is an equation true for all values of the variable". So then when I simplify/solve the equation, if they equal then I know it's an Identity, and if they dont equal then they're now an identity. (I chose a to equal 2 and b to equal 4, and did the work on a separate piece of paper)
Does that reasoning make sense? Because I've been on this slide for like 30 mins and it says I still havent sorted all the cards correctly .
Would really appreciate some help, thank you. (The photo is what I sorted, but still some are not sorted correctly.)

If p(x) is the total value of the production when there are x workers in a plant, then the average productivity of the workforce at the plant is a(x) = p(x) x . (a) find a'(x). a'(x) = xp'(x) − p(x) x a'(x) = xp'(x) − p(x) x2 a'(x) = p'(x) − p(x) x a'(x) = xp'(x) − p'(x) x2 a'(x) = p'(x) − xp(x) x2 why does the company want to hire more workers if a'(x) > 0? a'(x) > 0 ⇒ a(x) is ; that is, the average productivity as the size of the workforce increases. (b) if p'(x) is greater than the average productivity, which of the following must be true? p'(x) − xp(x) > 0 p'(x) − xp(x) < 0 xp'(x) − p'(x) > 0 xp'(x) − p(x) < 0 xp'(x) − p(x) > 0
