यदि (x=-5) समीकरण \(3x^2+px-20=0\) का मूल है, तो (p) का मान क्या होगा?

If (x=-5) is a root of \(3x^2+px-20=0\), what is the value of (p)?

Explanation opens after your attempt
Correct Answer

A. (11)

Step 1

Concept

Putting (x=-5) gives (75-5p-20=0). Hence (p=11).

Step 2

Why this answer is correct

The correct answer is A. (11). Putting (x=-5) gives (75-5p-20=0). Hence (p=11).

Step 3

Exam Tip

(x=-5) रखने पर (75-5p-20=0) मिलता है। इससे (p=11) है।
