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:
.
-x%28-x%28x-a%29-%28a-x%29%29
-%28-2%29%28-%28-2%29%28%28-2%29-%28-5%29%29-%28%28-5%29-%28-2%29%29%29
Now that we've substituted the values, we convert -(-) into postives.
2%282%28-2%2B5%29-%28-5%2B2%29%29
Let's solve what is inside the two smallest parenthesis.
2%282%283%29-%28-3%29%29
Now multiply 2 and 3 above, so we get:
2%286-%28-3%29%29
Remember: deducting a negative is the same as adding its positive so -(-3)=3
2%286%2B3%29
Add numbers inside the parenthesis shown above, so we get:
2%2A9
Now multiply
18 <--- this is our final result! :)
