\(7-4x+2x^2\) को मानक द्विघात रूप में लिखें।
Write \(7-4x+2x^2\) in standard quadratic form.
Explanation opens after your attempt
A. \(2x^2-4x+7\)correct standard form
Concept
In standard form, the \(x^2\) term comes first, then the (x) term, then the constant term. In exams arrange terms in descending powers.
Why this answer is correct
The correct answer is A. \(2x^2-4x+7\) / correct standard form. In standard form, the \(x^2\) term comes first, then the (x) term, then the constant term. In exams arrange terms in descending powers.
Exam Tip
मानक रूप में \(x^2\) वाला पद पहले, फिर (x) वाला पद और फिर स्थिर पद आता है। परीक्षा में पदों को घात के घटते क्रम में रखें।
