`(2a^2-12a+18/3a^2-12) xx (a^2+a-6/4a^2-36)`

`=(2a^2-12a+6a^2-12)xx(a^2+a-3/2a^2-36)`

`=(2a^2+6a^2-12a-12)xx(a^2-3/2a^2+a-36)`

`=(8a^2-12a-12)xx(-1/2a^2+a-36)`

which is simplified form of the given expression in terms of factors.

Problem should read:

(2a^2 - 12a + 18)/(3a^2 - 12) times (a^2 + a - 6)/(4a^2 - 36)
