यदि (p(x)=2x-2-7x+3), तो शून्यकों का योग क्या है?
If (p(x)=2x-2-7x+3), what is the sum of its zeroes?
Explanation opens after your attempt
A. \(\frac{7}{2}\)
Concept
For \(ax^2+bx+c\), the sum of zeroes is \(-\frac{b}{a}\). Here \(-\frac{-7}{2}=\frac{7}{2}\).
Why this answer is correct
The correct answer is A. \(\frac{7}{2}\). For \(ax^2+bx+c\), the sum of zeroes is \(-\frac{b}{a}\). Here \(-\frac{-7}{2}=\frac{7}{2}\).
Exam Tip
द्विघात \(ax^2+bx+c\) में शून्यकों का योग \(-\frac{b}{a}\) होता है। यहाँ \(-\frac{-7}{2}=\frac{7}{2}\) है।
