Classifying Polynomials

Degree of a Polynomial The degree of a polynomial is calculated by finding the largest exponent in the polynomial.

Degree of a Polynomial (Each degree has a special “name”) 9

Degree of a Polynomial (Each degree has a special “name”) 9 No variable Constant

Degree of a Polynomial (Each degree has a special “name”) 9 8 x No variable Constant 1 st degree Linear

Degree of a Polynomial (Each degree has a special “name”) 9 8 x 7 x 2 + 3 x No variable Constant 1 st degree Linear 2 nd degree Quadratic

Degree of a Polynomial (Each degree has a special “name”) 9 8 x 7 x 2 + 3 x 6 x 3 – 2 x No variable Constant 1 st degree Linear 2 nd degree Quadratic 3 rd degree Cubic

Degree of a Polynomial (Each degree has a special “name”) 9 8 x 7 x 2 + 3 x 6 x 3 – 2 x 3 x 4 + 5 x – 1 No variable Constant 1 st degree Linear 2 nd degree Quadratic 3 rd degree Cubic 4 th degree Quartic

Degree of a Polynomial (Each degree has a special “name”) 9 8 x 7 x 2 + 3 x 6 x 3 – 2 x 3 x 4 + 5 x – 1 2 x 5 + 7 x 3 No variable Constant 1 st degree Linear 2 nd degree Quadratic 3 rd degree Cubic 4 th degree Quartic 5 th degree Quintic

Degree of a Polynomial (Each degree has a special “name”) 9 8 x 7 x 2 + 3 x 6 x 3 – 2 x 3 x 4 + 5 x – 1 2 x 5 + 7 x 3 5 xn No variable Constant 1 st degree Linear 2 nd degree Quadratic 3 rd degree Cubic 4 th degree Quartic 5 th degree Quintic 6 th degree or higher “nth” degree

Let’s practice classifying polynomials by “degree”. 1. 2. 3. 4. 5. 6. 7. 8. 9. POLYNOMIAL 3 z 4 + 5 z 3 – 7 15 a + 25 185 2 c 10 – 7 c 6 + 4 c 3 - 9 2 f 3 – 7 f 2 + 1 15 y 2 9 g 4 – 3 g + 5 10 r 5 – 7 r 16 n 7 + 6 n 4 – 3 n 2 1. 2. 3. 4. 5. 6. 7. 8. 9. DEGREE NAME Quartic Linear Constant Tenth degree Cubic Quadratic Quartic Quintic Seventh degree The degree name becomes the “first name” of the polynomial.

Let’s practice classifying a polynomial by “number of terms”. Polynomial 1. 2. 3. 4. 5. 6. 7. 8. 15 x 2 e 8 – 3 e 7 + 3 e – 7 6 c + 5 3 y 7 – 4 y 5 + 8 y 3 64 2 p 8 – 4 p 6 + 9 p 4 + 3 p – 1 25 h 3 – 15 h 2 + 18 55 c 19 + 35 1. 2. 3. 4. 5. 6. 7. 8.
