Question

can anyone give me the correct answer and step by step to this math problems. write in lowest terms. 8z-24 divided by 4z-12. and q2-4q divided by 4q-q2.

Answer 1

It's just simplifying
What do you get if you do 2(4z-12) using the distributive property?

Answer 2

this is what I gotten 2(4z2-12z-3) with 2-3 under it.

Answer 3

What

Answer 4

Just do this, apply the distributive property to 2(4z-12)

Answer 5

That's 2(4z)-2(12), which equals 8z-24

Answer 6

that is what I have 2(4z-12z) with z-3 on the bottom. is that correct?

Answer 7

No, the answer for the first one is simply 4z-12, because 4z-12 is half of 8z-24

Answer 8

thank you

Answer 9

can someone give me the step by step to 5ksquare-13k-6 divided by 5k+2

Answer 10

First factor 5k^2-13k-6

Answer 11

ok

Answer 12

will be it 25k-55ksquare-26k-6

Answer 13

What in the world are you doing?

Answer 14

I do not no that's why I'm needing help please.

Answer 15

Explain to me how you got that answer

Answer 16

To factor we have to set the equation to equal zero

Answer 17

ok
how do i do that?

Answer 18

The equation is 5k^2-13k-6, to set that to equal zero you simply make it
5k^2-13k-6=0

Answer 19

Do you know how to factor this?

Answer 20

what do I do with the 5k+2 on the bottom of the problem

Answer 21

no I do not math is not my good subject and its hard for me.

Answer 22

Leave the 5k+2 for later

Answer 23

this is why I ask for step by step to see how the problem is solved. and I thank you for helping me.

Answer 24

So if we factor that first equation we get (5k+2)(k-3)

Answer 25

So far we've got

\[\frac{ (5k+2)(k-3) }{5k+2}\]

Answer 26

What can you cancel out?

Answer 27

the 5k's

Answer 28

and the 2

Answer 29

The "5k+2"s actually. You can't cancel out just parts, those are complete, in parentheses. So what are you left with?

Answer 30

K-3

Answer 31

thank you . now can you help me with q2-4q divided by 4q-q2

Answer 32

Is that q squared or q times 2?

Answer 33

q square

Answer 34

So, can we switch the order in q^2-4q so that it's reversed?

Answer 35

I firgured the answer out , I cancel all out and it left me with _1

Answer 36

is that correct what I did?

Answer 37

Yes, -1. Good job

Answer 38

okay in the first problem with the 4z-12 and the bottom is the same so do I cancel those out and write undefined.

Answer 39

No,
\[\frac{ 8z-24 }{ 4z-12 }\]

And since 4z-12 is half of 8z-24, the answer is 2

Answer 40

how did you get 2

Answer 41

I got the answer to my own question because 2 is divisable to 8 and 24.

Answer 42

now can you help me with this problem x+2 divided by x-4 do I cancel the the 2 and 4 out?

Answer 43

can anyone find the value of the variable for which the rational expression is undefined.
x+2 divided by x-8
