Question

А) 4(2а – b) – 3(2а + 3b) =

Answer 1

Ответ:

$4(2a - b) - 3(2a + 3b) = 8a - 4b + 6a - 9b = 2a - 12b$

Answer 2

To simplify the expression 4(2a - b) - 3(2a + 3b), you can use the distributive property to expand and then combine like terms:

First, distribute the constants outside the parentheses:

4 * 2a - 4 * b - 3 * 2a - 3 * 3b

Now, multiply the constants:

8a - 4b - 6a - 9b

Next, combine like terms. Group the "a" terms and the "b" terms:

(8a - 6a) - (4b + 9b)

Now, simplify each group separately:

2a - 13b

So, the simplified expression is:

2a - 13b
