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
C. (9)
Concept
(p(3)=9-3a+18=0), so (27=3a) and (a=9). After substitution, solve the simple linear equation.
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.
Exam Tip
(p(3)=9-3a+18=0), इसलिए (27=3a) और (a=9)। मान रखने के बाद सरल रैखिक समीकरण हल करें।
