Expression: 4(p q) (3a-b) 6(p q) (2b-3a)

Explanation:
Let's break down the given expression step by step:

Step 1:
Evaluate 4(p q) by applying the distributive property. The distributive property states that a(b + c) = ab + ac.

4(p q) = 4p + 4q

So, the expression becomes:
(4p + 4q) (3a - b) 6(p q) (2b - 3a)

Step 2:
Evaluate (4p + 4q) (3a - b) by applying the distributive property again.

(4p + 4q) (3a - b) = 4p(3a - b) + 4q(3a - b)

Using the distributive property, we can further simplify it as:

= 12ap - 4bp + 12aq - 4bq

So, the expression becomes:
12ap - 4bp + 12aq - 4bq 6(p q) (2b - 3a)

Step 3:
Evaluate 6(p q) by applying the distributive property.

6(p q) = 6p + 6q

So, the expression becomes:
12ap - 4bp + 12aq - 4bq + 6p + 6q (2b - 3a)

Step 4:
Evaluate (2b - 3a) by applying the distributive property.

(2b - 3a) = 2b - 3a

So, the final simplified expression is:
12ap - 4bp + 12aq - 4bq + 6p + 6q + (2b - 3a)

Final Expression:
The final expression is: 12ap - 4bp + 12aq - 4bq + 6p + 6q + 2b - 3a

In summary:
The given expression, 4(p q) (3a-b) 6(p q) (2b-3a), can be simplified to 12ap - 4bp + 12aq - 4bq + 6p + 6q + 2b - 3a.
