Question 428994
find the LCD of the fraction 
5 over x-6 ' 7over x squared-12x+36
-----
(5/(x-6)) ; 7/[(x-6)^2]
---
LCD = (x-6)^2
It is the smallest expression into 
which you can divide (x-6) and (x-6)^2
----------------------------------------------------------
5 over 7ab power of 5' 2 over 7a power of 3 b to power of 3
---
(5/(7ab^5)) ; (2/(7a^3b^3))
---
LCD = 7a^3b^5
==============================
7 over x squared-x-6 + 5 over x-3
(7/[(x-3)(x+2)] ; 5/(x-3)
---
LCD = (x-3)(x+2)
==============================
5 over 6a squared + 1 over 6ab 
---
(5/(6a^2)) + (1/(6ab))
----
LCD = 6a^2b
