1) How can polynomials be classified based on the number of terms and on the degree of the terms? 2) When a complex number is in the denominator, why is it necessary to multiply by the conjugate?

3) How do extraneous solutions arise from radical equations?

(I don't mind if only 3 is answered, or 2 is answered. Though if all 3 is answered that'd be greatly appreciated, these are the only questions I don't understand)​

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.
