Question

:) 4a(2a - 3b) - 6b(5b - 2a).

Answer 1

Ответ:

8a^2 - 30b^2 (^ - это степень)

Пошаговое объяснение:

= 4а*2а - 4а*3b - 6b*5b + 6b*2a= 8a^2 - 12ab - 30b^2 + 12ab = 8a^2-30b^2

Answer 2

To simplify the expression, let's start by expanding the terms:

4a(2a - 3b) - 6b(5b - 2a)

First, distribute 4a to the terms inside the parentheses:

= 4a * 2a - 4a * 3b - 6b(5b - 2a)

= 8a^2 - 12ab - 6b(5b - 2a)

Next, distribute -6b to the terms inside the parentheses:

= 8a^2 - 12ab - 6b * 5b + 6b * 2a

= 8a^2 - 12ab - 30b^2 + 12ab

Now, we can combine like terms:

= 8a^2 - 12ab + 12ab - 30b^2

The terms -12ab and +12ab cancel each other out, leaving us with:

= 8a^2 - 30b^2

So, the simplified expression is 8a^2 - 30b^2.
