समीकरण \(x^2-11x+30=0\) में मूलों की पहचान के लिए कौन-सी संख्या जोड़ी उपयोगी है?

Which pair of numbers is useful to identify the roots of \(x^2-11x+30=0\)?

Explanation opens after your attempt
Correct Answer

A. (5) और (6)(5) and (6)

Step 1

Concept

\(5\cdot6=30\) and (5+6=11). Because the middle term is negative, the factors are ((x-5)(x-6)).

Step 2

Why this answer is correct

The correct answer is A. (5) और (6) / (5) and (6). \(5\cdot6=30\) and (5+6=11). Because the middle term is negative, the factors are ((x-5)(x-6)).

Step 3

Exam Tip

\(5\cdot6=30\) और (5+6=11) होता है। ऋण मध्य पद के कारण गुणनखंड ((x-5)(x-6)) बनते हैं।
