Topic: Polynomials
Main Idea: Multiplying Polynomial by a Polynomial
Aim:
RECALL
(
) floor needs a carpet. It is in the
shape of a rectangle. The rectangle is x + 3 feet
wide and x + 4 feet long. (
) is not
sure how much carpeting to buy.
What does name need to find out in order to
determine how much carpeting to buy?
Before you find the area of the floor, find the
product of (x + 4)(a)
Now find the area of the floor.
Multiply:
(2d + 5)(d + 4)
Simplify (x + 5)2
NOTES
4) From the product 4d
and 3d, subtract 6d2
Drill: Multiply:
SUMMARY:
If time:
a) What is the product of (x + y) and (x – y)?
b) What is the product of (x + y) and (x + y)?
c) What is the product of (3x - 4) and (4x + 5)?
d) Find the area of a rectangle whose length is 2x + 3 and width is x + 1?
