यदि (p(x)=x-2+ax+b), (p(-2)=0) और (p(5)=0), तो (a+b) क्या है?
If (p(x)=x-2+ax+b), (p(-2)=0), and (p(5)=0), what is (a+b)?
Explanation opens after your attempt
A. (-13)
Concept
The zeros are (-2) and (5), so the polynomial is ((x+2)(x-5)=x-2-3x-10). Hence (a+b=-3-10=-13).
Why this answer is correct
The correct answer is A. (-13). The zeros are (-2) and (5), so the polynomial is ((x+2)(x-5)=x-2-3x-10). Hence (a+b=-3-10=-13).
Exam Tip
शून्य (-2) और (5) हैं, इसलिए बहुपद ((x+2)(x-5)=x-2-3x-10) है। अतः (a+b=-3-10=-13)।
