द्विघात बहुपद जिसके शून्यक \(\frac{2}{3}\) और \(-\frac{5}{4}\) हैं, कौन सा हो सकता है?
Which can be a quadratic polynomial whose zeroes are \(\frac{2}{3}\) and \(-\frac{5}{4}\)?
Explanation opens after your attempt
A. \(12x^2+7x-10\)
Concept
The sum is \(-\frac{7}{12}\) and the product is \(-\frac{5}{6}\). So \(12x^2+7x-10\) is correct.
Why this answer is correct
The correct answer is A. \(12x^2+7x-10\). The sum is \(-\frac{7}{12}\) and the product is \(-\frac{5}{6}\). So \(12x^2+7x-10\) is correct.
Exam Tip
शून्यकों का योग \(-\frac{7}{12}\) और गुणनफल \(-\frac{5}{6}\) है। इसलिए \(12x^2+7x-10\) सही है।
