Question

-2х умножить на -3у -4(х-2) (3х-1) умножить на 2

Answer 1

Ответ:

Пошаговое объяснение:

-2х*3у=-6ху

-4(х-2)=-4х+8

(3х-1)*2=6х-2

Answer 2

To simplify the expressions, let's start by solving each of them step by step:

Expression 1: -2x multiplied by -3y

When multiplying two negative numbers, the result is positive. So, we have:

-2x * -3y = 6xy

Expression 2: -4(x-2) multiplied by (3x-1) * 2

First, simplify the expression -4(x-2):

-4(x-2) = -4x + 8

Now, multiply (3x-1) by 2:

(3x-1) * 2 = 6x - 2

Next, multiply -4x + 8 by 6x - 2:

(-4x + 8) * (6x - 2) = -24x^2 + 8x + 48x - 16

Simplifying further:

-24x^2 + 8x + 48x - 16 = -24x^2 + 56x - 16

So, the final expression is -24x^2 + 56x - 16.

To summarize: -2x * -3y simplifies to 6xy. -4(x-2) * (3x-1) * 2 simplifies to -24x^2 + 56x - 16.
