\(8x^2-23x-15=0\) को हल करने में कौनसा गुणनखंड रूप सही है?
Which factorised form is correct for solving \(8x^2-23x-15=0\)?
Explanation opens after your attempt
A. ((8x+5)(x-3)=0)
Concept
((8x+5)(x-3)=8x-2-19x-15), so it is not for the given equation. In exams, verify each option by expansion.
Why this answer is correct
The correct answer is A. ((8x+5)(x-3)=0). ((8x+5)(x-3)=8x-2-19x-15), so it is not for the given equation. In exams, verify each option by expansion.
Exam Tip
((8x+5)(x-3)=8x-2-19x-15) नहीं बल्कि यह विस्तार गलत होगा; सही गुणनखंड ((8x+5)(x-3)) से (-24x+5x=-19x) बनता है। परीक्षा में विस्तार से हर विकल्प जांचें।
