Baljit builds a square frame that is 1 inch wider than twice the width of a square frame from the store. He writes the area enclosed by his frame with the polynomial 4 x 2+ 4x+ 1. a. Factor the polynomial that Baljit wrote. Explain how the factorization yields an expression for the width of the frame Baljit builds. b.What is a variable expression for the area enclosed by the frame from the store? Explain how you know.
