Question

Janelle wants to enlarge a square graph that she has made so that a side of the new graph will be 1 inch more than twice the original side s. What trinomial represents the area of the enlarged graph?

Answer 1

(s+1)^2 = s^2 + 2s + 1

Answer 2

(s+1)(s+1) = s^2 + s + s + 1

that equals s^2 + 2s + 1.

you are absolutely correct! good job!
