Question

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

Answer 1

(2а-3в)(-3в+2а)=(2а-3в)(2а-3в)=(2а-3в)²=

4а² - 12ав + 9в².

(а-в)²=а²-2ав+в².

Answer 2

To simplify the given expression, you can use the distributive property (also known as the FOIL method) to multiply the two binomials:

(2a - 3b) * (-3b + 2a)

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

Now, let's multiply the terms:

-6ab + 4a^2 + 9b^2 - 6ab

Combine like terms:

-12ab + 4a^2 + 9b^2

So, the simplified expression is:

-12ab + 4a^2 + 9b^2
