Completely factorise \(2x^3-18x\).
Explanation opens after your attempt
A. (2x(x-3)(x+3))सही रूप
Concept
First take out (2x), and \(x^2-9\) is a difference of squares. In exams check the inside identity after the common factor.
Why this answer is correct
The correct answer is A. (2x(x-3)(x+3)) / सही रूप. First take out (2x), and \(x^2-9\) is a difference of squares. In exams check the inside identity after the common factor.
Exam Tip
पहले (2x) निकालें और \(x^2-9\) वर्गों का अंतर है। परीक्षा में समान गुणनखंड के बाद अंदर की पहचान देखें।
