Math Problem Statement
Solution
To solve this problem, let's find the area of a rectangle with height and width . The area can be found by multiplying the height and width:
-
Set up the multiplication:
-
Distribute across each term in the width polynomial:
So, multiplying gives: .
-
Distribute across each term in the width polynomial:
So, multiplying gives: .
-
Combine all terms: Now we add the two results from the distribution step:
-
Combine like terms:
- term:
- terms:
- terms:
- Constant term:
So, the area of the rectangle is:
This is the polynomial that represents the area of the rectangle.
