c. the related polynomial equation has a total of four roots, two roots are complex and two roots are real.
d. the related polynomial equation has a total of two roots, both roots are real and have a multiplicity of 2.
e. the related polynomial equation has a total of three roots, two roots are complex and one root is real.
f. the related polynomial equation has a total of four roots, two roots are complex and one root is real with a. multiplicity of 2.

A

Step-by-step explanation:

The polynomial (x+4)(x-1)(x-2)(x-4) has zeros at x=-4,1,2,4.

The related polynomial equation is (x+4)(x-1)(x-2)(x-4)=0.

In order for this equation to be true at least one of the factors must by 0 that is the only way a product can be zero (if one of it's factors is).

So you wind up needing to solve these 4 equations:

x+4=0            x-1=0          x-2=0             x-4=0

x=-4                 x=1              x=2                   x=4

First equation, I subtracted 4 on both sides.

Second equation, I added 1 on both sides.

Third equation, I added 2 on both sides.

Fourth equation, I added 4 on both sides.

-4,1,2,4 are all integers

Integers are real numbers.

So A.

i think it would be 43 movies that would have to be watched.

step-by-step explanation:

think about it. for the second plan, every month is 8 dollars. 8 x 12= 96. so thats the number for the second plan. now for the first plan, its annual meaning you have to pay 10 dollars every year. so now you have to get an equivalent amount of 86 since 96-10=86. 86 divided by 2 since every movie costs 2$ then you would have to watch 43 movies a year to get the same as the second plan. i really hoped this . have a wonderful day as well!

answer: you need the equation in the question so i can answer it
