यदि (p(x)=x-2+ax+b), (p(2)=0) और (p(4)=0), तो (a+b) क्या है?
If (p(x)=x-2+ax+b), (p(2)=0), and (p(4)=0), what is (a+b)?
Explanation opens after your attempt
C. (2)
Concept
The zeros are (2) and (4), so the polynomial is ((x-2)(x-4)=x-2-6x+8). Hence (a+b=-6+8=2).
Why this answer is correct
The correct answer is C. (2). The zeros are (2) and (4), so the polynomial is ((x-2)(x-4)=x-2-6x+8). Hence (a+b=-6+8=2).
Exam Tip
शून्य (2) और (4) हैं, इसलिए बहुपद ((x-2)(x-4)=x-2-6x+8) है। अतः (a+b=-6+8=2)।
