Question

An expression is shown below:

2x3y + 18xy − 10x2y − 90y

Part A: Rewrite the expression so that the GCF is factored completely. (4 points)

Part B: Rewrite the expression completely factored. Show the steps of your work. (6 points)

Answer 1

can anyone give me the answer

Answer 2

Answer 3

@Nnesha

Answer 4

hmm what's a GCF?

Answer 5

greatest common factor

Answer 6

\(\bf 2x^3y+18xy-10x^2y-90y\) <---see any here

Answer 7

2

Answer 8

so... let us take it out then :) what do you end up with?

Answer 9

2y(x−5)(x2+9)

Answer 10

well... hmm to be exact.. notice, all terms have a "y" as well, so 2y

Answer 11

hmmm how... did you get 2y(x−5)(x2+9)?

Answer 12

srry i just used mathway

Answer 13

hmm ok... did the instructions on the exercise said you meant to use mathway and write down the output?

Answer 14

i just wrote the equation

Answer 15

an u just ell me the answer for A plz

Answer 16

really have to get this done

Answer 17

so... take the GCF and see what you end up with :)

Answer 18

idk

Answer 19

help plz

Answer 20

\(\bf 2x^3y+18xy-10x^2y-90y\implies {\color{blue}{ 2}}x^3{\color{blue}{ y}}+{\color{blue}{ 2}}\cdot 9x{\color{blue}{ y}}-{\color{blue}{ 2}}\cdot 5x^2{\color{blue}{ y}}-{\color{blue}{ 2}}\cdot 45{\color{blue}{ y}}\)

so.. .take out the GCF... and see what's left

Answer 21

ohhh ok
