Question

simplify completely!??

Answer 1

x^2 + 4x – 5 20x - 12
----------------- divided by ----------------
5x^2 – 8x + 3 x^2 – 6x - 55

Answer 2

mmm factor each term separately
like x^2 + 4x - 5 = (x+5)(x-1)

Answer 3

Ok, yea, the first one was the only one I could do, like how would I simplify the others? They don't seem to be able to factor..?

Answer 4

also dividing is like multiplying the flipped
like 3 divided by 2 = 3 times (1/2)
so you would get
(x+5)(x-1) 4(5x-3)
---------- x ----------
(5x-3)(x-1) (x-11)(x+5)

Answer 5

whoops

Answer 6

(x+5)(x-1) (x-11)(x+5)
---------- x ----------
(5x-3)(x-1) 4(5x-3)

Answer 7

so first of all you need to know how divide two fractions ?

Answer 8

yes @jigglypuff314 multiplie first by second inversed

Answer 9

but now that I look at it @jhonyy9 it would factor better if the original was multiplication and not division >.<

Answer 10

yes ATTENTION !!! SO THAN WILL BE MORE EASY ...

Answer 11

Oh, I do see how you did that; now do I cancel the terms?

Answer 12

yup :)

Answer 13

Ok, I 'm getting x - 11 / 4,
but that isn't an option:/

Answer 14

ehh
(x+5)(x-1) (x-11)(x+5)
---------- x ----------
(5x-3)(x-1) 4(5x-3)

only the ^^ (x-1) cancel out... nothing else really does :/

Answer 15

Really? I thought all numbers that are the same like (x + 5) are cancelled?

Answer 16

well if it were (x+5) over (x+5) then it would cancel
but they're both on top >.<
which was why I was commenting to jhonyy9 easier about how it would be easier if the original wasn't division :P

Answer 17

Ok, then I'm confused. How do I finish solving it then?

Answer 18

(x+5)(x-1) (x-11)(x+5) (x-11)(x+5)^2
---------- x ---------- = --------------
(5x-3)(x-1) 4(5x-3) 4(5x-3)^2

Answer 19

@poiuyt123 do you can rewrite your exercise newly probably correctly ?

Answer 20

I'm not sure, do I re-distribute the numerator?

Answer 21

err if what I gave wasn't right
then might I ask what are the options? :3

Answer 22

sure, it's:

4 over x + 5
4 (x – 1) over x + 5
4 over x – 11
4 (x + 5) over x - 11

Answer 23

err then are you sure it was asking a "divided by" in the original?

Answer 24

oh my gosh, yes I just realized, it Is a multiplication symbol! I'm sorry!:(
Will that make it a different process?

Answer 25

lol not too much different
just
(x+5)(x-1) 4(5x-3)
---------- x ----------
(5x-3)(x-1) (x-11)(x+5)

Answer 26

lol, so This one Is 4 over x - 11 ?

Answer 27

yup :)

Answer 28

Yay, thanks so much! And sorry about the error on my part. :3

Answer 29

it's fine ;)
