यदि (p(x)=x-2-2(k+1)x+k-2) के शून्यकों का योग (10) है, तो (k) क्या है?

If the sum of zeroes of (p(x)=x-2-2(k+1)x+k-2) is (10), what is (k)?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

The sum of zeroes is (2(k+1)), so (2(k+1)=10) and (k=4). Handle the negative sign carefully in the formula.

Step 2

Why this answer is correct

The correct answer is A. (4). The sum of zeroes is (2(k+1)), so (2(k+1)=10) and (k=4). Handle the negative sign carefully in the formula.

Step 3

Exam Tip

शून्यकों का योग (2(k+1)) है, इसलिए (2(k+1)=10) और (k=4)। सूत्र लगाते समय ऋण चिह्न संभालें।
