Which middle step is correct while solving (13x^2-52x+9=0) by completing the square?(13x^2-52x+9=0) को पूर्ण वर्ग विधि से हल करने में सही मध्य चरण कौनसा है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: ((x-2)^2=\frac{43}{13})((x-2)^2=\frac{43}{13})
First (x^2-4x+\frac{9}{13}=0) is obtained, then ((x-2)^2=\frac{43}{13}). In exams, divide by (a) first when (a\neq1).पहले (x^2-4x+\frac{9}{13}=0) बनता है, फिर ((x-2)^2=\frac{43}{13}) मिलता है। परीक्षा में (a\neq1) हो तो पहले (a) से भाग दें।
