If the zero of (p(x)=(k-2)x+9) is (-3), what is the value of (k)?
Explanation opens after your attempt
A. (5)
Concept
From (-3(k-2)+9=0), we get (k=5). Substitute the zero into the polynomial and set it to (0).
Why this answer is correct
The correct answer is A. (5). From (-3(k-2)+9=0), we get (k=5). Substitute the zero into the polynomial and set it to (0).
