यदि (p(x)=ax+b) का शून्यक (5) है और (a=-2), तो (b) क्या है?
If the zero of (p(x)=ax+b) is (5) and (a=-2), what is (b)?
Explanation opens after your attempt
A. (10)
Concept
From (p(5)=0), (5a+b=0). Substituting (a=-2) gives (b=10).
Why this answer is correct
The correct answer is A. (10). From (p(5)=0), (5a+b=0). Substituting (a=-2) gives (b=10).
Exam Tip
(p(5)=0) से (5a+b=0) होगा। (a=-2) रखने पर (b=10) मिलता है।
