Correct Answer

B. (-10)

Step 1

Concept

From (p(2)=0), (2a+b=0). Substituting (a=5) gives (b=-10).

Step 2

Why this answer is correct

The correct answer is B. (-10). From (p(2)=0), (2a+b=0). Substituting (a=5) gives (b=-10).

Step 3

Exam Tip

(p(2)=0) से (2a+b=0) होगा। (a=5) रखने पर (b=-10) मिलता है।
