\(15x^2+16x+4=0\) में मध्य पद का सही विभाजन कौनसा है?
What is the correct splitting of the middle term in \(15x^2+16x+4=0\)?
Explanation opens after your attempt
A. \(15x^2+10x+6x+4=0\)
Concept
Here (ac=60) and (10+6=16), so (16x) is split as (10x+6x). In exams, check both sum (b) and product (ac).
Why this answer is correct
The correct answer is A. \(15x^2+10x+6x+4=0\). Here (ac=60) and (10+6=16), so (16x) is split as (10x+6x). In exams, check both sum (b) and product (ac).
Exam Tip
यहां (ac=60) और (10+6=16), इसलिए (16x) को (10x+6x) में तोड़ते हैं। परीक्षा में योग (b) और गुणनफल (ac) दोनों जांचें।
