Question

(x+y)* + 2x(3х - у) при х = 1, y = N2.

Answer 1

Ответ:

При значениях, которые есть в задании ответ =7

Answer 2

To evaluate the expression (x + y) + 2x(3x - y) when x = 1 and y = N2, we can substitute the given values into the expression and perform the necessary calculations.

Replacing x with 1 and y with N2, we have:

(1 + N2) + 2(1)(3(1) - N2)

Simplifying further:

1 + N2 + 2(1)(3 - N2)

Now, we can simplify the expression inside the parentheses:

1 + N2 + 2(3 - N2)

Next, we distribute the 2:

1 + N2 + 6 - 2N2

Combine like terms:

7 - N2

Therefore, the simplified expression is 7 - N2 when x = 1 and y = N2.
