Answer 5

Like, k=-8 and whatever the otehr one is? Do we do them in separate brackets, or merge em?

Answer 6

no?

Answer 7

Are you able to figure that one out? ITs either quadratic formula or complex trinomials.

Answer 8

ARe you able to do the previously stated (complex trinomials)?

Answer 9

\[3 k^3+19 k^2-33 k+56\] method?

Answer 10

Cloud factoring?

Answer 11

am I right?

comebined like turms first

Answer 24

@pokemon, foil is a trick math teacher play on students. the sooner you forget it the better

Answer 25

lol then what method should I used then?

Answer 26

this is your problem, as you have written above
\[(k+8)(3k^2-5k+7)\] is that correct?

Answer 27

yes it is :D

and your job it to multiply

Answer 29

yup distributive

Answer 30

you will have to do 6 multiplications, and then combine like terms

Answer 31

yes

Answer 32

first i would multiply everything in this line
\[(3k^2-5k+7)\]by k namely find
\[k(3k^2-5k+7)\]

Answer 33

this is the method I use, hope it helps :)

Answer 34

i got 3k^3-6k+7

Answer 36

forgot the negative sign

Answer 37

forgot e were multiplying

Answer 38

ok a mistake.
\[k\times (-5k)=-5k^2\]

Answer 39

likewise
\[k\times 7=7k\]

Answer 40

so we 8*(3k^2-5k+7)

Answer 41

24k^2-40k+7

Answer 42

right that is the second part

Answer 43

you forgot
\[8\times 7\]

Answer 44

good work sate and pokemon
