Answer 2

Given,

The expression: (x+7) (x-5).

To find,

The solution using an identity.

Solution,

We can easily solve this problem by following the given steps.

According to the question,

We have the following expression:

(x+7) (x-5)

Now, to expand this expression, we will use the following identity:

(x+a) (x+b) = x²+(a+b)x+ab

In this case, we have a = 7 and b = -5.

Now, using this identity, we have:

x²+(7-5)x+7(-5)

x²+2x-35

Hence, after solving the expression: (x+7) (x-5) using an identity, we get (x²+2x-35).
