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।
