WebBy induction on the degree, the theorem is true for all nonconstant polynomials. Our next two theorems use the truth of some earlier case to prove the next case, but not necessarily the truth of the immediately previous case to prove the next case. This approach is called the \strong" form of induction. Theorem 3.2.

WebAn enumerative induction or, to use its more formal name, an induction by simple enumeration has the form Some As are B Therefore, All As are B.
