I need help simplifying these algebraeic expressions:?

Question

1. ((u-5)/(2u+4))/((u+3)/(3u+6))(6/(3u-15))

2. ((7t^2-28t)/(2t^2-5t-12))((6t^2-t-15)/(49t^2))

3. ((18x^2-6x)/(3x^4))((10x^2-7x-12)/(15x^2+7x-4

I appreciate it! Best answer goes to first right answer with explanation!

Answer 1

1.
_________________________________


((u-5)/(2u+4)) / ((u+3)/(3u+6))(6/(3u-15))


((u-5)/(2u+4))
------------------------------------
((u+3)/(3u+6))(6/(3u-15))


(u-5)(3u+6)(3u-15)
----------------------------
(u+3) * 6 * (2u+4)


(u-5)(3u+6)(3u-15)
------------------------
(u+3) * 4 * (3u+6)


(u-5)(3u-15)
------------------
(u+3) * 4


3u²-30u+75
-----------------
4*(u+3)

((7t^2-28t)/(2t^2-5t-12)) ((6t^2-t-15)/(49t^2))


(7t^2-28t)(6t^2-t-15)
---------------------------
(2t^2-5t-12)(49t^2)


-35t^3 + 84t^2 + 224t
--------------------------
98t^4 - 245t^3 - 588t^2


-35t^2 + 84t + 224
-----------------------------
98t^3 - 245t^2 - 588t


-5t^2 + 12t + 32
----------------------
14t^3 - 35t^2 - 84t


-5t^2 + 12t + 32
-------------------------
7 * (2t^3 - 5t^2 - 12t)

((18x^2-6x)/(3x^4)) ((10x^2-7x-12)/(15x^2+7x-4))


(18x^2-6x)(10x^2-7x-12)
----------------------------------
(3x^4)(15x^2+7x-4)


184x^4 - 186x^3 - 174x^2 + 72x
-------------------------------------------
45x^6 + 21x^5 - 12x^4


184x^3 - 186x^2 - 174x + 72
---------------------------------------
45x^5 + 21x^4 - 12x^3

Answer 2

i believe the expressions are cut off at the end
