What is the value attained when (6w2 + 4) (22z – 2) is subtracted from (2z – 3) (4w2 – z)?

Some rules to remember while multiplying algebraic expression are:
- The product of two factors with the same signs will be positive, and the outcome of multiplying two terms with two, unlike signs, will be negative.
- If x is variable and a, b are positive integers then, (xa * xb) = x(m +n)
