Let’s practice classifying polynomials by “degree”.POLYNOMIAL

1. 3z4 + 5z3 – 72. 15a + 253. 1854. 2c10 – 7c6 + 4c3 - 95. 2f3 – 7f2 + 16. 15y2

7. 9g4 – 3g + 58. 10r5 –7r9. 16n7 + 6n4 – 3n2

DEGREE NAME1. Quartic2. Linear3. Constant4. Tenth degree5. Cubic6. Quadratic7. Quartic8. Quintic9. Seventh degree

The degree name becomes the “first name” of the polynomial.
