यदि (p(x)=x-2-(m+3)x+12) के शून्यक (3) और (4) हैं, तो (m) का मान क्या है?

If the zeroes of (p(x)=x-2-(m+3)x+12) are (3) and (4), what is (m)?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

The sum of zeroes is (7), which equals (m+3). Therefore, (m=4).

Step 2

Why this answer is correct

The correct answer is B. (4). The sum of zeroes is (7), which equals (m+3). Therefore, (m=4).

Step 3

Exam Tip

शून्यकों का योग (7) है और यह (m+3) के बराबर है। इसलिए (m=4) मिलेगा।
