Question

X квадрат +2x-2 при x=-3

Answer 1

(-3)в квадрате+2*(-3)-2=9-6-2=1

Answer 2

To find the value of the expression $X^2 + 2X - 2$ when $X = -3$, we simply substitute $X$ with $-3$ and perform the calculation:

$X^2 + 2X - 2$ at $X = -3$

$(-3)^2 + 2(-3) - 2$

$9 - 6 - 2$

$3 - 2$

$1$

So, when $X = -3$, the value of the expression $X^2 + 2X - 2$ is $1$.
