Answer 2

Given:

Simplify using identities: (x+3)(x-4)​

To find:

We need to solve this question using the identities.

Solution:

Here, the identity is  

(X+a)(X-b)= X²+ (a-b)X - ab

Now, a = 3  

         b=4

Therefore, we substitute the terms and solve this equation.

(X+3)(X-4) = X²+(3-4)X - (3)(4)

Here, we will solve this equation

(X+3)(X-4) = X² -X -12

Here, the solution is

X² - X -12.
