Answer 1

a. 6xy(2x^2y^2-4xy^2) If you need to multiply 6xy and 2x^2y^2 & 6xy and 4xy^2. You will get 12x^3y^3-24x^2y^3. b. Factorization is not complete because 6xy is not the greatest common factor. c. Complete factor: 12x^2y^3(x-2y).

Answer 2

Explanation:

Given that Ian factored

`12x^3y^3 - 24x^2y^3`

as

`6xy(2x^2y^2 - 4xy^2).`

We find that inside still there are common factors for the two terms.

We can find 2 as common factor and for x, the term x and for y it is y^2

So correct factorisation would be

`12x^2y^3(x-2)`
