If (x + 2) is a factor of x3 − 6x2 + kx + 10, k equals

Step-by-step explanation:

for a given k we got

and we are looking for k so that

let s estimate

we can identify the terms do

terms in

   1 = a

terms in

   -6=b+2a

terms in x

   k=2b+c

constant term

   10 = 2c

it gives c = 10/2=5 and as a=1 b = -6-2a=-6-2=-8

so k = -2*8+5=-16+5=-11

the answer is k=-11

and then

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.

you 're wlecome! : )

i can not answer the question due to the fact that you spelled "carton" as "cartoon", a cartoon is something you watch on tv, a carton is a box that holds things. and also you've been waiting for this question for a while so why don't you get off your lazy a** and try to figure it out for yourself for once!
