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
B. (4)
Concept
The sum of zeroes is (7), which equals (m+3). Therefore, (m=4).
Why this answer is correct
The correct answer is B. (4). The sum of zeroes is (7), which equals (m+3). Therefore, (m=4).
Exam Tip
शून्यकों का योग (7) है और यह (m+3) के बराबर है। इसलिए (m=4) मिलेगा।
