Question

Х^2-х^3, если х=-0,2

Answer 1

0,2^2-0,2^3=0.04-0.008=0,032

Answer 2

To find the value of the expression $x^2 - x^3$ when $x = -0.2$, we simply substitute $x$ with the given value and perform the calculation.

$x^2 - x^3 = (-0.2)^2 - (-0.2)^3$

Now, let's calculate the values step-by-step:

$x^2 = (-0.2)^2 = 0.04$

$x^3 = (-0.2)^3 = -0.008$

Finally, we can compute the expression:

$x^2 - x^3 = 0.04 - (-0.008) = 0.04 + 0.008 = 0.048$

So, $x^2 - x^3$ when $x = -0.2$ is equal to 0.048.
