Question

factorise the following:- (p-3)²-q²​

Answer 1

Answer:

(p-3+q) (p-3-q)

Explanation:

By using the method of difference of two squares we can find the result.i.e. X²-Y²= (x+y)(x-y).

therefore, in (p-3)²-q²= (p-3+q)(p-3-q).

Answer 2

(p-3)² - q²

Using a² - b² = (a-b)(a+b), factor the given expression.

= (p - 3 - q) × (p - 3 + q)

The required factorisation.

Hope this helps! (:
