The area of a small square sample of carpet is 16w² + 8w – 8 in yards. Which of the following could be the length of the sample? A. w – 1 B. 4w – 2 C. 4w + 2 D. 8w – 2 Could you give me a step by step answer
16w^2 + 8w - 8 (4w - 2)(4w + 4) therefore your answer is B
Thanks I understand how to do that now.
Your welcome :) it's cause the area of a square is sxs so all you do is factorize it
