-0,2²-4*3*(-0,1)

To solve this expression, we can start by simplifying each term:

-0.2² = -0.2 * -0.2 = 0.04

-4 * 3 * (-0.1) = -12 * (-0.1) = 1.2

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

0.04 - 1.2

Finally, we can subtract 1.2 from 0.04:

0.04 - 1.2 = -1.16

Therefore, the value of the expression -0.2² - 4 * 3 * (-0.1) is -1.16.
