यदि (p(x)=x-2+kx+6) और (p(2)=0), तो (k) क्या है?
If (p(x)=x-2+kx+6) and (p(2)=0), what is (k)?
Explanation opens after your attempt
A. (-5)
Concept
(p(2)=4+2k+6=0), so (2k=-10) and (k=-5). Substitute the zero and form an equation.
Why this answer is correct
The correct answer is A. (-5). (p(2)=4+2k+6=0), so (2k=-10) and (k=-5). Substitute the zero and form an equation.
Exam Tip
(p(2)=4+2k+6=0), इसलिए (2k=-10) और (k=-5)। शून्य की शर्त में मान रखकर समीकरण बनाएं।
