If (x^2-3x+h=0) has equal roots, what is the value of (h)?यदि (x^2-3x+h=0) के मूल बराबर हैं, तो (h) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (h=\frac{9}{4})(h=\frac{9}{4})
For equal roots, (D=0), so (9-4h=0) and (h=\frac{9}{4}). In exams, the (D=0) method remains valid even with fractional answers.बराबर मूलों के लिए (D=0), अतः (9-4h=0) और (h=\frac{9}{4})। परीक्षा में भिन्न उत्तर आने पर भी (D=0) पद्धति सही रहती है।
