Mr. Deyo

2. Learning Target
By the end of the period, I will add and subtract polynomials in order to solve problems.
I will demonstrate this by taking notes in a graphic organizer and by solving problems in a group/pair activity.

6. Notes:

7. 3 15x + x3 – Rewrite a polynomial Example 1
Write so that the exponents decrease from left to right. Identify the degree and leading coefficient of the polynomial.

8. 3 15x + x3 – 15x + x3 – 3 Rewrite a polynomial Example 1
Write so that the exponents decrease from left to right. Identify the degree and leading coefficient of the polynomial.
SOLUTION
The polynomial can be written as The table shows the degree of each term. The greatest degree is 3, so the degree of the polynomial is 3, and the leading coefficient is .
15x + x3 – 3 1
