यदि \(x^2-24x+108=0\) को पूर्ण वर्ग विधि से हल किया जाए, तो सही मध्य चरण कौनसा है?
If \(x^2-24x+108=0\) is solved by completing the square, which middle step is correct?
Explanation opens after your attempt
Correct Answer
A. ((x-12)2=36)
Concept
Adding (144) to \(x^2-24x=-108\) gives ((x-12)2=36). In exams, add the square of half the coefficient to both sides.
Why this answer is correct
The correct answer is A. ((x-12)2=36). Adding (144) to \(x^2-24x=-108\) gives ((x-12)2=36). In exams, add the square of half the coefficient to both sides.
Exam Tip
\(x^2-24x=-108\) में (144) जोड़ने पर ((x-12)2=36) मिलता है। परीक्षा में आधे गुणांक का वर्ग दोनों पक्षों में जोड़ें।
