समीकरण \(\frac{2}{5}x^2+\frac{1}{5}x-2=0\) का पूर्णांक गुणांकों वाला रूप कौन-सा है?
What is the form with integer coefficients for \(\frac{2}{5}x^2+\frac{1}{5}x-2=0\)?
Explanation opens after your attempt
Correct Answer
A. \(2x^2+x-10=0\)
Concept
Multiply the whole equation by (5) to remove denominator (5). This gives \(2x^2+x-10=0\).
Why this answer is correct
The correct answer is A. \(2x^2+x-10=0\). Multiply the whole equation by (5) to remove denominator (5). This gives \(2x^2+x-10=0\).
Exam Tip
हर (5) हटाने के लिए पूरे समीकरण को (5) से गुणा करें। इससे \(2x^2+x-10=0\) मिलता है।
