51*39*28=55692
55692*95/100=52907.4
52907+3455.75= 56363.15
55692-56363.15=-671.15

The factorization of 12a^3b^2 +18a²b^2 – 12ab^2 is 
<u>Solution:</u>
Given, expression is 
We have to factorize the given expression completely.
Now, take the expression

Taking
as common term,

Taking "a" as common term,

Taking "6" as common term,

Splitting "3a" as "4a - a" we get,


Hence, the factored form of given expression is 
Answer:
