Correct Answer

C. (28)

Step 1

Concept

From (p(7)=0), (7a+b=0). Substituting (a=-4) gives (b=28).

Step 2

Why this answer is correct

The correct answer is C. (28). From (p(7)=0), (7a+b=0). Substituting (a=-4) gives (b=28).

Step 3

Exam Tip

(p(7)=0) से (7a+b=0) होगा। (a=-4) रखने पर (b=28) मिलता है।
