5-85.
Create a generic rectangle.
Put the products on the outside.
Multiply the expressions.
Write the areas as a sum.
x² + 2x + 8x + 16
(x + 2)(x + 8) = x² + 10x + 16
Follow the steps in part (a).
Use the Distributive Property.
x(y + 10) = xy + 10x
Follow the steps in part (a).
(2x + 3)(3x + 4) = 6x² + 17x + 12
