यदि (p(x)=ax+b) का शून्यक (-3) है और (a=2), तो (b) क्या है?
If the zero of (p(x)=ax+b) is (-3) and (a=2), what is (b)?
Explanation opens after your attempt
A. (6)
Concept
From (p(-3)=0), (-3a+b=0). Substituting (a=2) gives (b=6).
Why this answer is correct
The correct answer is A. (6). From (p(-3)=0), (-3a+b=0). Substituting (a=2) gives (b=6).
Exam Tip
(p(-3)=0) से (-3a+b=0) होगा। (a=2) रखने पर (b=6) मिलता है।
