यदि (p(x)=ax+b) और \(a\ne0\), तो इसका शून्य क्या होगा?
If (p(x)=ax+b) and \(a\ne0\), what will be its zero?
Explanation opens after your attempt
B. \(-\frac{b}{a}\)
Concept
From (ax+b=0), we get \(x=-\frac{b}{a}\). Remember the general formula but do not miss the sign.
Why this answer is correct
The correct answer is B. \(-\frac{b}{a}\). From (ax+b=0), we get \(x=-\frac{b}{a}\). Remember the general formula but do not miss the sign.
Exam Tip
(ax+b=0) से \(x=-\frac{b}{a}\) मिलता है। सामान्य सूत्र याद रखें लेकिन संकेत न भूलें।
