\(30x^2-61x+30=0\) में मध्य पद का सही विभाजन कौनसा है?

What is the correct splitting of the middle term in \(30x^2-61x+30=0\)?

Explanation opens after your attempt
Correct Answer

A. \(30x^2-36x-25x+30=0\)

Step 1

Concept

Here (ac=900) and (-36+(-25)=-61), so the correct split is (-36x-25x). In exams, even for large (ac), match both sum and product.

Step 2

Why this answer is correct

The correct answer is A. \(30x^2-36x-25x+30=0\). Here (ac=900) and (-36+(-25)=-61), so the correct split is (-36x-25x). In exams, even for large (ac), match both sum and product.

Step 3

Exam Tip

यहां (ac=900) और (-36+(-25)=-61), इसलिए सही विभाजन (-36x-25x) है। परीक्षा में बड़ा (ac) हो तो भी योग और गुणनफल दोनों मिलाएं।
