यदि (p(x)=2x-2-4\sqrt{2}x+4), तो शून्यकों का योग क्या है?
If (p(x)=2x-2-4\sqrt{2}x+4), what is the sum of its zeroes?
Explanation opens after your attempt
A. \(2\sqrt{2}\)
Concept
The sum is \(-\frac{b}{a}=-\frac{-4\sqrt{2}}{2}=2\sqrt{2}\). Do not forget the coefficient (a).
Why this answer is correct
The correct answer is A. \(2\sqrt{2}\). The sum is \(-\frac{b}{a}=-\frac{-4\sqrt{2}}{2}=2\sqrt{2}\). Do not forget the coefficient (a).
Exam Tip
योग \(-\frac{b}{a}=-\frac{-4\sqrt{2}}{2}=2\sqrt{2}\) है। गुणांक देखते समय (a) को मत भूलें।
