Correct Answer

A. (-4)

Step 1

Concept

(p(x)+q(x)=5x+a-6). Substituting (x=2) gives (10+a-6=0), so (a=-4).

Step 2

Why this answer is correct

The correct answer is A. (-4). (p(x)+q(x)=5x+a-6). Substituting (x=2) gives (10+a-6=0), so (a=-4).

Step 3

Exam Tip

(p(x)+q(x)=5x+a-6) है। (x=2) रखने पर (10+a-6=0) से (a=-4) मिलता है।
