Answer:
The given expression is simplified as
Step-by-step explanation:
Here,the given expression is (x+9)(x -9)
Using the ALGEBRAIC IDENTITY:
Now, here in the given expression (x + 9)(x -9)
Comparing it the left side of the identity,
we get a = x
and b = 9
The right side of the equation is
Substituting the value of a and b, we get
⇒
=
Hence, the given expression is simplified as
