If (a - b)/(a + b) = 2 and b = 1,

this is pretty straight forward, so I'm thinking I why people might get this one wrong. I think it's what Chris said in the video: you need to remember to keep the parenthesis when you multiply 2 by (a+1), if you don't, it will be wrong. also, I've gotten questions like this wrong before because my scratch paper was not neat and I confused myself, so don't do that. Another thing is to mark on your paper when you are adding or subtracting on either side of the equal sign. i was the person who never did this because I know how to add and subtract. the thing you may not understand is that this is a timed test with high stakes, so you will forget about the smallest details if you don't write it down.
