, is the zero of the function. What is the corresponding factor?
Use (b) to find another factor.
Try using a generic rectangle. A 2 by 3 rectangle, labeled as follows: left edge, x, minus 2, interior top, left, x, cubed.
Labels added: top edge, left, x, squared, interior bottom, left, negative 2, x, squared, interior top, middle, negative 4, x squared.
Labels added: top edge, middle, negative 4, x, interior bottom, middle, 8, x, interior top, right, negative x.
Labels added: top edge, right, negative 1, interior bottom, right, 2.
