यदि किसी मोनिक द्विघात समीकरण के दोनों मूल (5) और (5) हैं तो समीकरण कौन सा है?
If both roots of a monic quadratic equation are (5) and (5), which equation is it?
Explanation opens after your attempt
Correct Answer
A. \(x^2-10x+25=0\)
Concept
If both roots are (5), the equation is ((x-5)2=0). Expanding it gives \(x^2-10x+25=0\).
Why this answer is correct
The correct answer is A. \(x^2-10x+25=0\). If both roots are (5), the equation is ((x-5)2=0). Expanding it gives \(x^2-10x+25=0\).
Exam Tip
दोनों मूल (5) हों तो समीकरण ((x-5)2=0) होगा। इसे खोलने पर \(x^2-10x+25=0\) मिलता है।
