यदि (p(x)=(k-6)x+18) का शून्यक (-3) है, तो (k) क्या है?
If the zero of (p(x)=(k-6)x+18) is (-3), what is (k)?
Explanation opens after your attempt
C. (12)
Concept
From (-3(k-6)+18=0), we get (k=12). Substitute the zero into the polynomial to form the equation.
Why this answer is correct
The correct answer is C. (12). From (-3(k-6)+18=0), we get (k=12). Substitute the zero into the polynomial to form the equation.
Exam Tip
(-3(k-6)+18=0) से (k=12) मिलता है। शून्यक को बहुपद में रखकर समीकरण बनाएं।
