Which condition is correct for ((k-1)x-2+3x+2=0) to remain quadratic?
Explanation opens after your attempt
Correct Answer
B. \(k\neq1\)
Concept
The coefficient of the quadratic term is ((k-1)), which must not be (0). Hence \(k\neq1\) is necessary.
Why this answer is correct
The correct answer is B. \(k\neq1\). The coefficient of the quadratic term is ((k-1)), which must not be (0). Hence \(k\neq1\) is necessary.
