Question

Divide and simply to lowest terms.

4x^2-16x/ 4x-3 / x-4/ 4x-3

Answer 1

hope so much that you know sure how need dividing two factors

Answer 2

do you know it ?

Answer 3

so multiplie by second inversed

ok ?

Answer 4

no, which is why I am asking. From what my chapter states, a/b / c/d = a/b * d/c

Answer 5

why ?

this is right sure

a/b/c/d = a/b *d/c

Answer 6

okay got that part, but now I have to simply 4x^2-16x/ x-4

Answer 7

yes so if you rewrite it what will get ?

Answer 8

I am not sure, I know the LCM would be either x or 4

Answer 9

rewrite it with this property that you need multiplie the first fraction with second inversed

and check what will get and what will can simplifie there

Answer 10

so then it would be 4x(x-4)/ x-4 ?

Answer 11

yes and multiplie by second inversed

Answer 12

so really it just equals 4x

Answer 13

4x(x-4) 4x -3
------- * ------- =
x-4 x-4

Answer 14

4x(x-4) * 4x-3

Answer 15

not right

Answer 16

where is the denominator ?

Answer 17

4x(x-4)*4x-3 over x-4

Answer 18

not right

Answer 19

you have simpolified from numerator the x-4

yes ?

Answer 20

okay

Answer 21

so than what will get ?

Answer 22

4x?

Answer 23

4x(x -4) 4x-3 4x(4x-3)
-------- * ------ = --------- = 4x
4x-3 x -4 4x -3

yes you are right

good luck

bye

Answer 24

thank you.

Answer 25

was my pleasure

hope so much that is understandably sure right

bye - bye
