Evaluate x to the second power minus 3x x=-2

x^2 - 3x

4 - 6 -2

4 - 6 = -2

To evaluate the expression x^2 - 3x when x = -2, you need to substitute the value of x into the expression and simplify.

The expression x^2 - 3x represents a quadratic equation. To find the value when x = -2, substitute -2 for x in the expression:

(-2)^2 - 3(-2)

Now, simplify the expression using the order of operations (PEMDAS/BODMAS):

(-2)^2 is equal to 4 (because -2 multiplied by -2 equals 4).

-3(-2) is equal to +6 (because -3 multiplied by -2 equals +6).

So, the simplified expression becomes:

4 + 6

Add the values together:

= 10

Therefore, when x = -2, the value of x^2 - 3x is equal to 10.
