Question

The lengths of two sides of a triangle are shown below:

Side 1: 3x2 - 4x - 1
Side 2: 4x - x2 + 5

The perimeter of the triangle is 5x3 - 2x2 + 3x - 8.

Part A: What is the total length of the two sides, 1 and 2, of the triangle? (4 points)

Part B: What is the length of the third side of the triangle? (4 points)

Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer. (2 points)

Answer 7

5x3 - 2x2 + 3x - 8
-(2x2 +4)
--------------------
5x^3 -4x^2 +3x -12

Answer 8

3x2 - 4x - 1
-x2 +4x + 5
------------------
2x^2 +4

Length of third side is found by subtracting this from perimeter
