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
Correct Answer

A. \(2\sqrt{2}\)

Step 1

Concept

The sum is \(-\frac{b}{a}=-\frac{-4\sqrt{2}}{2}=2\sqrt{2}\). Do not forget the coefficient (a).

Step 2

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).

Step 3

Exam Tip

योग \(-\frac{b}{a}=-\frac{-4\sqrt{2}}{2}=2\sqrt{2}\) है। गुणांक देखते समय (a) को मत भूलें।
