Answer 3

hat is the largest number that divides evenly into 3x3 and −48x?

Answer 4

what*

Answer 5

3?

Answer 6

plz help

Answer 7

Good so

What is the highest degree of x that divides evenly into 3x3 and −48x?

Answer 8

help with what?? @rainbow_rocks03

Answer 9

3?

Answer 10

\[3x^3-48x=3x\left( x^2-16 \right)=?\]
\[a^2-b^2=\left( a+b \right)\left( a-b \right)\]

Answer 11

nope degree not number @Nin

Answer 12

help with question

Answer 13

48?

Answer 14

need to understand how to get my answer

Answer 15

@rainbow_rocks03 please post your question in the ask a question bo

Answer 16

I did

Answer 17

nope its X b.c thats the degree so now we multiplying the results above, the GCF is 3x

Answer 18

yes please, we are working on something!! @rainbow_rocks03

Answer 19

okay!@jagr2713

Answer 20

@jagr2713

Answer 21

So now we factor out the GCF so put the GCF as the first term and then in teh parentheses divide each term by the GCF

\[3x (\frac{ 3x2 }{ 3x }+\frac{ -48x }{ 3x }\]

Answer 22

So now we Simplify each term in parentheses and get?

Answer 23

so 2+ 16x?

Answer 24

nope we simplify each term in parentheses and get


3x(x2-16)

Answer 25

@jagr2713

Answer 26

So this ik you remember so we have x2−16 fits the form a2−b2
Rewrite it where a=x and b=4
3x(x2−42)

Answer 27

So now use the difference of squares \[a ^{2}-b ^{2}=(a+b)(a-b)\]

Answer 28

Plug it in :D

Answer 29

(x+4)(x-4)
