Question

(-1/3b)×(-9b^2+3b-12)​

Answer 1

Ответ: -1/3b × (-9b²+3b-12) = -1/3b × (-9b²) - 1/3b × 3b + 1/3b × (-12) = 3b³ - b² + 4b

Answer 2

To simplify the expression (-1/3b) × (-9b^2 + 3b - 12), you can distribute the (-1/3b) to each term inside the parentheses:

(-1/3b) × (-9b^2 + 3b - 12) = (-1/3b) × (-9b^2) + (-1/3b) × (3b) + (-1/3b) × (-12)

First, let's simplify each term:

(-1/3b) × (-9b^2) = (1/3) × (9b) × b = 3b^2

(-1/3b) × (3b) = (1/3) × (3b) × b = -b^2

(-1/3b) × (-12) = (1/3) × (12) = 4

Now, let's combine the simplified terms:

3b^2 + (-b^2) + 4 = 2b^2 + 4

Therefore, the simplified expression is 2b^2 + 4.
