Verified answer

Answer:

To evaluate the expression a - ab, we substitute the given values of a and b:

a = 2, b = -2

a - ab = 2 - (2)(-2)

Simplifying the expression:

a - ab = 2 + 4

a - ab = 6

Therefore, when a = 2 and b = -2, the value of a - ab is 6.

Answer:

If a = 2 and b = -2, you can calculate the value of a - ab as follows:

a - ab = 2 - (2 * -2) = 2 - (-4) = 2 + 4 = 6

So, when a = 2 and b = -2, the value of a - ab is 6.
