Multiply the expressions.
Use a generic rectangle to multiply.
In a rectangle,
Added labels to interior: top left, x squared, top right, 1, x, bottom left, 1, x, bottom right, negative 1.
The total area of the generic rectangle, or
and .Then use a generic rectangle to multiply that result by .
2 by 2 square, left edge labeled, top, 2, x squared, bottom, + 2, x, Bottom edge labeled, left, x, right, + 1.
Added labels to interior: top left, 2, x to the third, top right, 2, x squared, bottom left, 2, x squared, bottom right, 2, x.
Now use a generic rectangle.
- and -intercepts of . The factors in part (c) should be useful.
-intercepts are where .
-intercept is where : from part (c).
Using the Zero Product Property:
