Which equation has (b=0) and (c<0)?
Explanation opens after your attempt
B. \(3x^2-12=0\)
Concept
In \(3x^2-12=0\), (b=0) and (c=-12). Treat the missing (x) term coefficient as (0).
Why this answer is correct
The correct answer is B. \(3x^2-12=0\). In \(3x^2-12=0\), (b=0) and (c=-12). Treat the missing (x) term coefficient as (0).
Exam Tip
\(3x^2-12=0\) में (b=0) और (c=-12) है। अनुपस्थित (x) पद का गुणांक (0) मानें।
