यदि (p(x)=kx-2+6x+9) और (p(-3)=0), तो (k) क्या है?

If (p(x)=kx-2+6x+9) and (p(-3)=0), what is (k)?

Explanation opens after your attempt
Correct Answer

A. (1)

Step 1

Concept

(p(-3)=9k-18+9=0), so (9k-9=0) and (k=1). Substitute the given zero to find the unknown coefficient.

Step 2

Why this answer is correct

The correct answer is A. (1). (p(-3)=9k-18+9=0), so (9k-9=0) and (k=1). Substitute the given zero to find the unknown coefficient.

Step 3

Exam Tip

(p(-3)=9k-18+9=0), इसलिए (9k-9=0) और (k=1)। दिए गए शून्य को रखकर अज्ञात गुणांक निकालें।
