Correct Answer

A. (6)

Step 1

Concept

From (p(-3)=0), (-3a+b=0). Substituting (a=2) gives (b=6).

Step 2

Why this answer is correct

The correct answer is A. (6). From (p(-3)=0), (-3a+b=0). Substituting (a=2) gives (b=6).

Step 3

Exam Tip

(p(-3)=0) से (-3a+b=0) होगा। (a=2) रखने पर (b=6) मिलता है।
