Question

Divide: 8xy^2 - 14y^2/2y

Answer 1

4xy^2-7y^2
4x-7
4xy-7y
4y-7x

Answer 2

\[\frac{ 8xy^{2} - 14y^{2} }{ 2y }\]
Right?

Answer 3

(8xy^2 - 14y^2) / 2y = 8xy^2 / 2y - 14y^2 / 2y = ?

Answer 4

Yup @jcpd910

Answer 5

How did you do that @jcpd910

Answer 6

I used the equation button.

Answer 7

do you get that?

Answer 8

Yeah, I'm solving it.

Answer 9

Okay, so first...
\[\frac{ 8xy^{2} }{ 2y } - \frac{ 14y^{2} }{ 2y }\]

Answer 10

Would it be b

Answer 11

No.

Answer 12

Ii'm getting 4xy - 2y

Answer 13

@phi

Answer 14

I just called in backup.

Answer 15

ok

Answer 16

@kirbykirby do you get this

Answer 17

14/2 = 7

Answer 18

Im getting B

Answer 19

4x-7

Answer 20

not quite,
\[ \frac{y^2}{y}=y^{2-1}=y\]

Answer 21

The y doesn't completely disappear

Answer 22

Ah, I used 4 not 14, I got the answer now.

Answer 23

[4xy^2-7y^2\]

Answer 24

kirby can explain it better.

Answer 25

So it has to be either A or C

Answer 26

Well @jcpd910 got most of it down already :) Just have to be careful when dividing out the y
You have a y^2 in the top and y in the bottom
when you divide that out, you do:
\(\large \frac{y^2}{y}=y^{2-1}=y\), so a y is still there

Answer 27

only y is left, not y^2

Answer 28

Would anything still be squared

Answer 29

Ok so c

Answer 30

yes

Answer 31

Thanks
