Correct Answer

C. (12)

Step 1

Concept

From (-3(k-6)+18=0), we get (k=12). Substitute the zero into the polynomial to form the equation.

Step 2

Why this answer is correct

The correct answer is C. (12). From (-3(k-6)+18=0), we get (k=12). Substitute the zero into the polynomial to form the equation.

Step 3

Exam Tip

(-3(k-6)+18=0) से (k=12) मिलता है। शून्यक को बहुपद में रखकर समीकरण बनाएं।
