Answer 1

Ответ:

Объяснение:

--3x(2-x)+(3x+1)(x-2)= -6x+3x²+3x²-6x+x-2=6х²-11х-2

Answer 2

$-3x(2-x)+(3x+1)(x-2)=-6x+3x^2+3x^2-6x+x-2=6x^2-11x-2$

Answer 3

To simplify the expression -3x(2-x) + (3x+1)(x-2), you can start by using the distributive property to expand the expressions inside the parentheses and then combine like terms. Here's the step-by-step simplification:

1. Expand -3x(2-x): -3x(2-x) = -3x * 2 + 3x * x = -6x + 3x^2

2. Expand (3x+1)(x-2): (3x+1)(x-2) = 3x * x + 3x * (-2) + 1 * x + 1 * (-2) = 3x^2 - 6x + x - 2 = 3x^2 - 5x - 2

Now, you have -6x + 3x^2 + 3x^2 - 5x - 2. Combine like terms:

-6x + 3x^2 + 3x^2 - 5x - 2 = (3x^2 + 3x^2) + (-6x - 5x) - 2 = 6x^2 - 11x - 2

So, the simplified expression is 6x^2 - 11x - 2.
