यदि (7x-2-(p+6)x+28=0) के मूल (2) और (2) हैं, तो (p) क्या होगा?

If the roots of (7x-2-(p+6)x+28=0) are (2) and (2), what is (p)?

Explanation opens after your attempt
Correct Answer

A. (p=22)

Step 1

Concept

The sum of roots is (4), and \(\frac{p+6}{7}=4\), so (p=22). In exams, use \(-\frac{b}{a}\) for the sum.

Step 2

Why this answer is correct

The correct answer is A. (p=22). The sum of roots is (4), and \(\frac{p+6}{7}=4\), so (p=22). In exams, use \(-\frac{b}{a}\) for the sum.

Step 3

Exam Tip

मूलों का योग (4) है और \(\frac{p+6}{7}=4\), इसलिए (p=22) है। परीक्षा में \(-\frac{b}{a}\) से योग निकालें।
