Explanation opens after your attempt
Correct Answer

A. (2)

Step 1

Concept

(p(3)=9+3k-15=0), so (3k=6) and (k=2). Use the zero condition to find the unknown.

Step 2

Why this answer is correct

The correct answer is A. (2). (p(3)=9+3k-15=0), so (3k=6) and (k=2). Use the zero condition to find the unknown.

Step 3

Exam Tip

(p(3)=9+3k-15=0), इसलिए (3k=6) और (k=2)। शून्य की शर्त लगाकर अज्ञात निकालें।
