Question

(1/2xy 2 -3a)(1/2xy 2 +3a)

Answer 1

Ответ:

Пошаговое объяснение:

не совсем понятно что внутри, но в любом случае это формула, если 2 после (1/2xy)^2

(1/2xy 2 -3a)(1/2xy 2 +3a) = $(1/2xy 2)^{2}$ - 9$a^{2}$

по формуле

(a-b)(a+b) = a*a - b*b

Answer 2

To simplify the expression (1/2xy^2 - 3a)(1/2xy^2 + 3a), we can use the formula for the difference of squares, which states that (a - b)(a + b) = a^2 - b^2.

Let's apply this formula to the given expression:

(1/2xy^2 - 3a)(1/2xy^2 + 3a)

Using the difference of squares formula, we have:

= (1/2xy^2)^2 - (3a)^2

Simplifying further:

= (1/4x^2y^4) - 9a^2

So the simplified expression is (1/4x^2y^4) - 9a^2.
