Correct Answer

C. (x(x-3)(x+3))

Step 1

Concept

First take (x) common to get (x\(x^2-9\)). Then factor (x-2-9=(x-3)(x+3)).

Step 2

Why this answer is correct

The correct answer is C. (x(x-3)(x+3)). First take (x) common to get (x\(x^2-9\)). Then factor (x-2-9=(x-3)(x+3)).

Step 3

Exam Tip

पहले (x) समान निकालकर (x\(x^2-9\)) मिलता है। फिर (x-2-9=(x-3)(x+3)) करें।
