Question:
If the roots of the quadratic equation \(x^2-(p+1)x+p=0\) are equal, then \(p\) is:
If the roots of the quadratic equation \(x^2-(p+1)x+p=0\) are equal, then \(p\) is:
Show Hint
Equal roots ⇒ discriminant zero.

- \(1/4\)
- \(-1/4\)
- 1
- \(-1\)
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Equal roots ⇒ discriminant \(=0\):
\[
(p+1)^2-4p=0 \Rightarrow (p-1)^2=0
\Rightarrow p=1
\]
