Explanation opens after your attempt
Correct Answer

B. \(4x^2+7x-9=0\)

Step 1

Concept

Moving (9) to the left makes it (-9). So the standard form is \(4x^2+7x-9=0\).

Step 2

Why this answer is correct

The correct answer is B. \(4x^2+7x-9=0\). Moving (9) to the left makes it (-9). So the standard form is \(4x^2+7x-9=0\).

Step 3

Exam Tip

दाईं ओर के (9) को बाईं ओर लाने पर (-9) बनता है। इसलिए मानक रूप \(4x^2+7x-9=0\) है।
