Polynomials - Guided Notes 11.2

Part 1: Find the degree of the polynomial.

1. 3x + 2

2. 4x3 + 17x - 5

3. 13x" + 5xn-2

4. 0.55x2 + 0.7x

5. 7x3 + 10x + 15

Answer 1

1. 3x + 2 - First degree

2. 4x3 + 17x - 5 - Third degree

3. 13x" + 5xn-2 - Second degree

4. 0.55x2 + 0.7x - Second degree

5. 7x3 + 10x + 15 - Third degree

Explanation:

The degree of a polynomial is given by the highest power of the given variable (x in this case) in the polynomial. All the elements are considered in selecting the highest power of x in the polynomials.

Considering all; the highest degree of x in the polynomials given is 3 while the lowest is 1 hence we have polynomials ranging from the first to third degrees.
