how do u solve this? (2n-6)^3

OpenStudy (karatechopper):

or simplify?

OpenStudy (anonymous):

finally..BIG IMRAN

OpenStudy (karatechopper):

yes!!

OpenStudy (anonymous):

I am just a visitor

OpenStudy (karatechopper):

OpenStudy (anonymous):

OpenStudy (karatechopper):

u mean i need help

OpenStudy (anonymous):

lol..pleas help us imran

OpenStudy (anonymous):

have you learned binomial theorem?

OpenStudy (karatechopper):

thanks

OpenStudy (anonymous):

yea..help armeena no..i havent learned tht

OpenStudy (anonymous):

then just multiply it out three times

OpenStudy (anonymous):

(2n-6)(2n-6)(2n-6)=

OpenStudy (karatechopper):

i know~ i did that! is the answer 8n^3-216?

OpenStudy (anonymous):

like how? i get soo confuzed tht way

OpenStudy (karatechopper):

or is it 8n-216?

OpenStudy (anonymous):

do first two first

OpenStudy (karatechopper):

4n+36?

OpenStudy (anonymous):

(2n-6)(2n-6)=4n^2-24n+36

OpenStudy (anonymous):

(2n-6)^3 8n^3-72n^2+32n-216

OpenStudy (anonymous):

kay..i got tht..

OpenStudy (karatechopper):

o i remember mnow!!

OpenStudy (anonymous):

then multiply the third one (2n-6)(4n^2-24n+36)

OpenStudy (karatechopper):

i remember how to do that!! lemme solve really quick!!

OpenStudy (anonymous):

(A+B)^3 A^3+3A^2B+3AB^2+B^3

OpenStudy (karatechopper):

is it -16n^2+168n-216?

OpenStudy (karatechopper):

anyone???????

OpenStudy (anonymous):

lols..jus leave it armeena..i will solve it later..
