Question

2(a+4b-3a)+4(a-b)-3(2c-3a) векторы

Answer 1

2(a+4b-3a)+4(a-b)-3(2c-3a)

2a+8b-6a+4a-4b-6c+9a

9a+4b

Answer 2

The expression you provided seems to be a combination of variables (a, b, and c) and constants. However, the notation used, "vectors," is not appropriate in this context. Vectors typically have direction and magnitude and are represented differently (e.g., with arrows on top).

It looks like you might be working with algebraic expressions. If that's the case, we can simplify the given expression by combining like terms:

2(a + 4b - 3a) + 4(a - b) - 3(2c - 3a)

Step 1: Distribute the coefficients:

2a + 8b - 6a + 4a - 4b - 6c + 9a

Step 2: Combine like terms (terms with the same variables raised to the same powers):

(2a - 6a + 9a) + 8b - 4b - 6c

Step 3: Perform the operations inside the parentheses:

5a + 4b - 6c

So, the simplified expression is: 5a + 4b - 6c.
