Correct Answer

A. ((8x-9y)(8x+9y))

Step 1

Concept

(64x-2=(8x)2) and (81y-2=(9y)2). So the factorisation is ((8x-9y)(8x+9y)).

Step 2

Why this answer is correct

The correct answer is A. ((8x-9y)(8x+9y)). (64x-2=(8x)2) and (81y-2=(9y)2). So the factorisation is ((8x-9y)(8x+9y)).

Step 3

Exam Tip

(64x-2=(8x)2) और (81y-2=(9y)2) है। इसलिए अंतर का गुणनखंड ((8x-9y)(8x+9y)) है।
