यदि किसी मोनिक द्विघात समीकरण के दोनों मूल (-4) और (-4) हैं तो समीकरण कौन सा है?
If both roots of a monic quadratic equation are (-4) and (-4), which equation is it?
Explanation opens after your attempt
Correct Answer
A. \(x^2+8x+16=0\)
Concept
If both roots are (-4), the equation is ((x+4)2=0). Expanding it gives \(x^2+8x+16=0\).
Why this answer is correct
The correct answer is A. \(x^2+8x+16=0\). If both roots are (-4), the equation is ((x+4)2=0). Expanding it gives \(x^2+8x+16=0\).
Exam Tip
दोनों मूल (-4) हों तो समीकरण ((x+4)2=0) होगा। इसे खोलने पर \(x^2+8x+16=0\) मिलता है।
