कौन सा रूप (a=3), (b=-4), (c=-2) को दर्शाता है?
Which form represents (a=3), (b=-4), (c=-2)?
Explanation opens after your attempt
A. \(3x^2-4x-2=0\)
Concept
Putting the values in \(ax^2+bx+c=0\) gives \(3x^2-4x-2=0\). Watch the sign of (b).
Why this answer is correct
The correct answer is A. \(3x^2-4x-2=0\). Putting the values in \(ax^2+bx+c=0\) gives \(3x^2-4x-2=0\). Watch the sign of (b).
Exam Tip
मानक रूप \(ax^2+bx+c=0\) में मान रखने पर \(3x^2-4x-2=0\) मिलता है। (b) का चिन्ह ध्यान रखें।
