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