Question

5/2(x-1), 1/2x, 3/2(x-1)^2=?

Answer 1

It is not clear what is being asked here. On the left side of the = sign are different three terms divided by commas. Commas do not represent a meaningful algebraic operation. Did you mean that three terms on the left are supposed to be added (+ sign)? Is the (x-1) supposed to be in the denominator of the first and third terms? If so, you should have used additional brackets or parentheses
