To solve your problem, replace every x with -2 and every a with -5 and then simplify.
Can you do it now?

-x[-x(x-a)-(a-x)]
Let x= -2
Let a= -5
.
In this problem we need to substitute the values of these two variables into the expression, then simplify it.
Be careful with the negatives. In order to avoid confusion, I will be using parenthesis to distinguish a negative number from a deduction.
Remember that when we deduct a negative number is the same as adding its positive value. Watch carefully:
.

Now that we've substituted the values, we convert -(-) into postives.

Let's solve what is inside the two smallest parenthesis.

Now multiply 2 and 3 above, so we get:

Remember: deducting a negative is the same as adding its positive so -(-3)=3

Add numbers inside the parenthesis shown above, so we get:

Now multiply
<--- this is our final result! :)
