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
Correct Answer

A. (-5)

Step 1

Concept

(p(2)=4+2k+6=0), so (2k=-10) and (k=-5). Substitute the zero and form an equation.

Step 2

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.

Step 3

Exam Tip

(p(2)=4+2k+6=0), इसलिए (2k=-10) और (k=-5)। शून्य की शर्त में मान रखकर समीकरण बनाएं।
