Question

Factor out the GCF from the polynomial 45x^3+81x^7-63x^2+18

Answer 1

check ur question

Answer 2

CF stands for common factor, there should be atleast two polynomials

Answer 3

? thats the exact question I. Don't think I wrote anything wrong.

Answer 4

it doesnt mean any thing to what in common in only one object

Answer 5

it's the problem I see and what it is asking for me to do.

Answer 6

the problems are like this
given two polynomials and to find a common factor between them which is greatest

Answer 7

I understand where you're going at, but on this problem of the math program I am using. it's what it says. >_>

Answer 8

ZakaullahUET is wrong. You have a polynomial with a bunch of terms. Finding the GCF means finding the number that is in ALL of your terms. In other words, what number goes into all of: 45, 81, 63, and 18? when you get that, you will "factor it out" and have "your number" times ( 45 divided by your number x^3 + 81 divided by your number x^7...and so on)

Answer 9

yes that's what it is asking, but i'm just cluless when it comes to factoring XD

Answer 10

ok, so what number goes into all of 45, 81, 63, and 18? give me that number and then i will help you write the full expression

Answer 11

9?

Answer 12

@masseyap11
thanks in refreshing our mind, i studied it 5 years before thats y i forgot

Answer 13

yup! so you divide EVERY TERM by 9 and put it on the outside like this: 9 times (45/9x^3 + 81/9 x^7 -63/9 x^2 + 18/2)

and zakaullauhUET its ok you were just trying to help!

Answer 14

oh ok

Answer 15

so isn't it 5x^3+9x^7-7x^2+9

Answer 16

yup!
