Answer:
C
Step-by-step explanation:
I substituted the x value with the different options. I kept doing that until the equation made sense.
For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.
Step-by-step explanation:
In order to prove the statement we can take any value of x and then solve the expression to see if it equal to -16 or not.
So,
Taking x = 2

Taking x = 5

Taking x= 10

Hence,
For any value of x the value of the expression (x–3)(x+7)–(x+5)(x–1) is equal to –16.
