Answer:
The answer is 48
Explanation:
Evaluating this expression basically means finding the product.
So you input -2 for x in the expression. Which is this one → 3(x)^2 - 6x
Once you input -2 for x it'll look like this ↓
3(-2)^2 - 6(-2)
Now all you have to do is solve and see what number you get! :)
3(-2) = -6
and
6(-2) = -12
so.. it now looks like this ↓
-6^2 - (-12)
and...
-6^2 = -36
so...
-36 - (-12) which equals 48
Kind of long heh- sorry but I hope I helped! :)
