यदि (p(x)=(k-4)x+15) का शून्यक (-5) है, तो (k) का मान क्या है?
If the zero of (p(x)=(k-4)x+15) is (-5), what is the value of (k)?
Explanation opens after your attempt
C. (7)
Concept
From (-5(k-4)+15=0), we get (k=7). Substitute the zero into the polynomial and set it to (0).
Why this answer is correct
The correct answer is C. (7). From (-5(k-4)+15=0), we get (k=7). Substitute the zero into the polynomial and set it to (0).
Exam Tip
(-5(k-4)+15=0) से (k=7) मिलता है। शून्यक को बहुपद में रखकर (0) करें।
