Need help ASAP. I should know how to do this but for some reason this stumped me. 30 PTS Keng is unhappy with his 3-inch-wide frame, so he decides to put a frame with a different width around his canvas. The total area of the canvas and the new frame is given by the polynomial h² + 8h + 12, where h represents the height of the canvas. Determine the width of the new frame. Show all of your work. Explain why you did each step.
