समीकरण \(10x^2-19x+6=0\) के मूल कैसे होंगे?
How will the roots of \(10x^2-19x+6=0\) be?
Explanation opens after your attempt
A. दो वास्तविक परिमेय और असमान ((D=121))Two real rational and distinct ((D=121))
Concept
Here (D=(-19)2-4(10)(6)=121). (D=121) is a perfect square, so the roots are rational.
Why this answer is correct
The correct answer is A. दो वास्तविक परिमेय और असमान ((D=121)) / Two real rational and distinct ((D=121)). Here (D=(-19)2-4(10)(6)=121). (D=121) is a perfect square, so the roots are rational.
Exam Tip
यहाँ (D=(-19)2-4(10)(6)=121) है। (D=121) पूर्ण वर्ग है, इसलिए मूल परिमेय हैं।
