Question

(-2)²+4*(-2)+3=сколько будет?

Answer 1

(-2)²+4*(-2)+3=4-8+3= -1

Answer 2

Let's solve the expression step by step:

(-2)² + 4*(-2) + 3

First, we'll calculate (-2)², which means -2 multiplied by itself:

(-2)² = (-2) * (-2) = 4

Next, we'll calculate 4 * (-2):

4 * (-2) = -8

Finally, we'll add 3 to the result:

-8 + 3 = -5

So, the final answer is -5.
