Question

Which of the following describes the roots of the polynomial function f (x) = (x + 2) squared (x minus 4) (x + 1) cubed?

Answer 1

do we have anychoices?

Answer 2

^ you don't necessarily need any

Answer 3

A –2 with multiplicity 2, 4 with multiplicity 1, and –1 with multiplicity 3
B –2 with multiplicity 3, 4 with multiplicity 2, and –1 with multiplicity 4
C 2 with multiplicity 2, –4 with multiplicity 1, and 1 with multiplicity 3
D 2 with multiplicity 3, –4 with multiplicity 2, and 1 with multiplicity 4

Answer 4

D

Answer 5

no

Answer 6

@Hero

Answer 7

what i do?

Answer 8

nothing lol, hero can help them

Answer 9

Answer 11

^

Answer 12

dont worry bout other tabs

Answer 13

Yes, that was from the chats for a completely different reason

Answer 14

A

Answer 15

\[f(x) = (x+2)^2 (x -4)(x+1)^3\]

do you think on these ?

Answer 16

so than yes - you see there this polynomial factorized - yes ?

how you think that you can calcule easy the roots of this polynomial ?
what you need to do with these factors ?

Answer 17

ok so for example than you have given a function formed from 3 terms f(x) = a*b*c

for what value of a or b or c will be this function equal zero ?
