The length of a flat screen TV is x2 + 1 feet. The width is x + 3 feet. What algebraic expression can be used to represent the area of the TV? Show all your work and explain how you arrived at your answer.

Note: Use the caret symbol "^", found above the 6 on your keyboard to represent exponents. For example, to type in x2 type the three keys x, ^, 2. The expression will look like this: x^2. Use the *, found above the 8 key to show multiplication. Do not use the letter x for multiplication, or it will get confused with the variable.
