Explanation:
Polynomials
- Polynomials can be classified by the degree of the polynomial. The degree of a polynomial is the degree of its highest degree term. So the degree of 2x3+3x2+8x+5 2 x 3 + 3 x 2 + 8 x + 5 is 3. A polynomial is said to be written in standard form when the terms are arranged from the highest degree to the lowest degree.
Adding Polynomials
- To add polynomials we simply add any like terms together. Step 1: Arrange each polynomial with the term with the highest degree first then in decreasing order of degree. Step 2: Group the like terms. Like terms are terms whose variables and exponents are the same.
