The implied domain of a rational function is the set of all real numbers except for the roots of the denominator. That’s because it doesn’t make sense to divide by 0. 197. Example. The implied domain of ... If ↵ is such a number, then we can multiply by q(↵)tofindthat p(↵)=0·q(↵)=0 In other words, ↵ is a root of p(x). Thus, the ...

Finding Real Roots of Polynomial Equations In Lesson 6-4, you used several methods for factoring polynomials. As with some quadratic equations, factoring a polynomial equation is one way to find its real roots. Recall the Zero Product Property from Lesson 5-3. You can find the roots, or solutions, of the polynomial equation P(x) = 0 by setting each
