Which of these pairs of numbers are two out of three integer-valued side lengths of a right triangle? Select all that are true. (Hint: for positive integers a, b, c, and k, ka, kb, and kc are side lengths of a right triangle if and only if a, b, and c are side lengths of a right triangle.) A 15, 21
B 12, 24
C 15, 39
D 16, 20
E 16, 24

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.
