EXPRESS EACH PRODUCT IN SIMPLEST STANDARD FORM (g-3) (2g^2+3g+3) show steps and explain me how to do this teach me how to do these types of problems I'm a bit puzzled from winter break?

OpenStudy (anonymous):

what's this?

OpenStudy (anonymous):

Do you need help expanding out the brackets?

OpenStudy (pokemon23):

like I have problems subtracting polynomials

OpenStudy (anonymous):

Okay what did you get when you multiplied everything out?

OpenStudy (pokemon23):

hold on a second I'm doing mission impossible two questions at the same time :(

OpenStudy (anonymous):

(g-3)(2g ^{2}+3g+3) \[2g ^{3}+3g ^{2}+ 3g-6g ^{2}-9g ^{2}-9\] Make sure to collect like terms \[2g ^{3}-3g ^{2}-6g -9\]

OpenStudy (pokemon23):

thank you so much roger roger remember to combine like terms gotcha I will memorized for my upcoming test:D this Thursday

OpenStudy (turingtest):

which question? this one?

OpenStudy (pokemon23):

ya :D

OpenStudy (pokemon23):

Explain this questions to me

OpenStudy (turingtest):

ok, here's the idea (g-3)(2g ^2+3g+3) first distribute the g to everything in parentheses then distribute the -3 to everything in parentheses. then add it together. wanna try?

OpenStudy (pokemon23):

so we used the distributive property?

OpenStudy (anonymous):

are you a visual learner pokemon?

OpenStudy (turingtest):

right, we distribute each term on the left to each term on the right then we add them together

OpenStudy (anonymous):

yes you use the distributing

OpenStudy (pokemon23):

so I got 2g63+3g^2+3g when distributive the g

OpenStudy (turingtest):

good, I assume the 6 is a typo... what about the -3 ?

OpenStudy (pokemon23):

2g^3+3g^2+3g

OpenStudy (turingtest):

right... continue.

OpenStudy (pokemon23):

-6g^2-9g-9

OpenStudy (turingtest):

good! now add them together.

OpenStudy (pokemon23):

2g^3+-4g^2-6g-9

OpenStudy (turingtest):

That's a little confusing, you have a few typos. seems very close though write out the step before: 2g^3+3g^2+3g -6g^2-9g-9=???

OpenStudy (pokemon23):

Its says to be written in standard from from highest degree to lowest (2g^3+3g^2+3g)+(-6g^2-9g-9)

OpenStudy (turingtest):

yes, but you still need to simplify though...

OpenStudy (anonymous):

Hey pokemon, this is how I learnt to expand. It's exactly the same as FOIL instead I use bunnies. It makes sure you don't leave any terms out. I hope it helps.

OpenStudy (turingtest):

that's pretty good zed

OpenStudy (pokemon23):

LOL bunny that kind of cute :D

OpenStudy (pokemon23):

now I see my mistake I subtracted wrong

OpenStudy (pokemon23):

instead of 4g^2 it should be -3g^2 because -6g^2+3g^2=3g^2

OpenStudy (pokemon23):

so the final answer is 2g^3-3g^2-6g-9

OpenStudy (turingtest):

nice! you got it! you forgot the negative sign in the post before it, but you fixed it in the answer.

OpenStudy (pokemon23):

thanks zed and turingtest :D

OpenStudy (turingtest):

Always a pleasure pokemon :D

OpenStudy (pokemon23):

ok i got two more :D

OpenStudy (pokemon23):

|dw:1325485181952:dw|

OpenStudy (turingtest):

is that\[\frac{1}{x-7}\]???

OpenStudy (pokemon23):

|dw:1325485220246:dw|
