### Algebra 6 Point 6

1. 1. 6.6 Simplifying Polynomials<br />Objective: <br /><ul><li>To classify polynomials according to the number of terms
2. 2. To simplify a polynomial and determine its degree
3. 3. To write a polynomial in ascending and descending order</li></ul>Frameworks: 10.P.3<br />
4. 4. Review: What is a monomial?<br />5<br />2x<br />⅔a3<br />
5. 5. What is a polynomial?<br />A polynomial is a monomial or the sum of two or more monomials<br />-5x3<br />a2 - 2ab<br />x2 + 2x - 1<br />
6. 6. Classifying polynomials<br />Polynomials can be classified according to their number of terms:<br />Monomial: -5x3 <br />Binomial: a2 - 2ab<br />Trinomial: x2 + 2x - 1<br />
7. 7. More terms<br />Like terms are terms with the same variable(s) raised to the same power(s).<br />A polynomial in simplest form if no two of its terms are like terms. <br />
8. 8. Simplify:<br />3y2- 5y - y2<br /> 2y2 – 5y<br />5x2 – 2x + 2 <br /> already in simplest form<br />10y + 4y2 - 5y2<br />3x2 + 2x2 - 1 <br />
9. 9. Degrees of monomials<br />The degree of a monomial is the sum of the exponents of all of its variables:<br />
10. 10. Degrees of polynomials<br />The degree of a polynomial is the same as the degree of its term with the greatest degree when the polynomial is in simplest form:<br />
11. 11. Simplify & give the degree:<br />3x3– 5x2 + 6x2 - 3x3 - 7 <br /> x2 – 5<br /> second degree<br />4y2– 6y + 7y4 - y2 – y4 <br />5x4+ 7 x – 1 - 3x3 - 5x4 - 3x + 2x3<br />3x2 + 2x2 - 1 <br />
12. 12. Simplify & give the degree & write the terms in descending order:<br />5x4+ 7x – 1 - 3x3 - 5x4 - 3x + 2x3<br />Group in descending order:<br />Combine like terms:<br />Degree? <br />
13. 13. Simplify & give the degree & write the terms in descending order:<br />8x5- 6x2 + 4x4 + 3x2+ 2x5 + x4 + 2x - 7<br />Group in descending order:<br />Combine like terms:<br />Degree? <br />
