Factor cheyalani chooste idi kudharadam ledu kada? Aagipovaalsina avasaram ledu. School worksheet lo fixed formula lo viluvalu pettinattule, ikkaadaa oka chinna kramanni anusarisdaam. Ichina expressionnu equationga, ante 3x^2 - 4x + 2 = 0ga teesukundaam. Idi quadratic equation. Kaabatti a = 3, b = -4, c = 2. Ante x^2 mundu sankhya 3, x mundu sankhya -4, chivari sthira sankhya 2. Ippudu quadratic formula lo ee viluvalanu pettandi: x = (-b +- sqrt(b^2 - 4ac))/(2a). Anduvalla x = (-(-4) +- sqrt((-4)^2 - 4(3)(2)))/(2(3)). Munduga discriminant, ante vargamoolam kinda migile b^2 - 4ac, lekkiddaam: 16 - 24 = -8. Idi sunna kante chinnadi. Anduke sqrt(-8) vastundi. i = sqrt(-1) kaabatti, sqrt(-8) = 2i sqrt(2). Ippudu x = (4 +- 2i sqrt(2))/6 = (2 +- i sqrt(2))/3. Plus teesukunte x = (2 + i sqrt(2))/3; minus teesukunte x = (2 - i sqrt(2))/3. Ive exact complex solutions. Negative discriminant valla real solutions levu. Kaabatti worksheet lo factor dorakakapovadam vaifalyam kaadu; ee lekka rendu complex samaadhaanalaku teesukellindi.
