Question

3хy-4x^2 если ,х =-2,y =-3

Answer 1

Ответ:

Это должно быть правильно

Answer 2

To evaluate the expression $3xy - 4x^2$ when $x = -2$ and $y = -3$, we substitute these values into the expression:

$3xy - 4x^2$ becomes $3 \times (-2) \times (-3) - 4 \times (-2)^2$.

Now, let's compute this step by step:

1. $3 \times (-2) \times (-3)$ equals $18$.
2. $-2$ squared is $4$, so $4 \times (-2)^2$ equals $16$.

Now, we can substitute these values back into the original expression:

$3xy - 4x^2 = 18 - 16 = 2$.
