Topic explanation

Standard explanation

Cubic degree 3. Leading coefficient a_n. A zero (root) is a number c with p(c)=0. Factor theorem next. Do not call 1x a polynomial.

Key points

• whole powers only
• degree = highest power
• divide: quotient + remainder, deg r smaller
• non-negative integer powers
• DEGREE AND ZEROS: Cubic degree 3. Leading coefficient a_n. A zero (root) is a number c with p(c)=0. Factor theorem nex
