​

Answer 1

Answer:

• Given - (x+ 4 )( x- 4)

• To find - solution of this

• Solution -

Using identity (a+ b)(a-b) = a^2 - b^2

x^2 - 4^2

x^2 - 16

Some more identities

(a+b)^2 = a^2 + b^2 + 2ab.

(a-b)^2 = a^2 + b^2 – 2ab.

a^2 – b^2 = (a+b) (a-b)

• If an equality holds true for all variable , it is called identity.
