​

Answer 1

Answer:

next time bracket ot assammese oto likhi diba mane mur olop kheli meli hoi English ot likhi dile....hehe xheikarone

Answer 2

Answer:

$\bold{ 2 {x}^{2} - 3x + 1 = 0 \: } \\ \\ \bold{\implies2 {x}^{2} - 2x - x + 1 = 0 \: }\\ \\ \bold{\implies2x(x - 1) - 1(x - 1) = 0 \: }\\ \\ \bold{\implies(x - 1)(2x - 1) = 0 \: }\\ \\ \bold{\therefore \: (x - 1)(2x - 1) = 0 \: }\\ \\ either, \: \: x - 1 = 0 \\ \implies \: x = 1 \: \: \: \: \: \: \: \: \: \: \\ \\ \\ or,2x - 1 = 0 \\ \implies x = \frac{1}{2} \\ \\ \therefore \: x = 1, \frac{1}{2} .$
