यदि (p(x)=x-2-ax+18) और (p(3)=0), तो (a) का मान क्या है?

If (p(x)=x-2-ax+18) and (p(3)=0), what is the value of (a)?

Explanation opens after your attempt
Correct Answer

C. (9)

Step 1

Concept

(p(3)=9-3a+18=0), so (27=3a) and (a=9). After substitution, solve the simple linear equation.

Step 2

Why this answer is correct

The correct answer is C. (9). (p(3)=9-3a+18=0), so (27=3a) and (a=9). After substitution, solve the simple linear equation.

Step 3

Exam Tip

(p(3)=9-3a+18=0), इसलिए (27=3a) और (a=9)। मान रखने के बाद सरल रैखिक समीकरण हल करें।
