If f(x) is reducible over Q , we know by Theorem 17.2 that there exist elements g(x),h(x) \in Z[x] such that f(x) = g(x)h(x), with 1 \leq deg(g),deg(h) < n. Let g = \sum^r b_i x^i,h=\sum^s c_ix^i ...
Letfbe a polynomial function with real coefficients and supposea+bi,b≠0a+bi,b≠0, is a zero off(x)f(x). Then, by the Factor Theorem,x−(a+bi)x−(a+bi)is a factor off(x)f(x). Forfto have real coefficients,x−(a−bi)x−(a−bi)must also be a factor off...
An infinite word u∈ Aω is said to be recurrent if each factor x of u has infinitely many occurrences in u, i.e. if u∈ A*xAω implies u∈ (A*x)ω. Theorem 2.14 Let φ : A+→ S be a morphism from A+ into a finite semigroup S and let u∈ Aω be an infinite word. ...
Divide that number into the dividend to find another factor. Keep factoring the factors to find the remaining factors. To factor an expression, first find the greatest common factor. Then, use techniques such as the rational root theorem or factoring by grouping to further factor the expression....

[16] proposed a factoriza- tion theorem for this WTA flavor definition, and validated it through one-loop order and in particular flavor channels at two-loops. Here, we extend the analysis of Ref. [16] through two-loop order, calculating all anomalous dimensions and thereby vali- dating ...

As you can see, every factor is a prime number, so the answer is right.It is neater to show repeated numbers using exponents:Without exponents: 2× 2 × 3 With exponents: 22× 3Example: What is the prime factorization of 147 ? Can we divide 147 exactly by 2? 147 ÷ 2 = 73½ ...
