\(x^2+10x+24\) को ((x+a)(x+b)) रूप में लिखने पर (a+b) क्या होगा?
When \(x^2+10x+24\) is written as ((x+a)(x+b)), what is (a+b)?
Explanation opens after your attempt
A. (10)correct sum
Concept
((x+a)(x+b)=x-2+(a+b)x+ab), so (a+b=10). In exams treat the middle coefficient as (a+b).
Why this answer is correct
The correct answer is A. (10) / correct sum. ((x+a)(x+b)=x-2+(a+b)x+ab), so (a+b=10). In exams treat the middle coefficient as (a+b).
Exam Tip
((x+a)(x+b)=x-2+(a+b)x+ab), इसलिए (a+b=10) है। परीक्षा में मध्य गुणांक को (a+b) मानें।
