2x²-4х+b=0
Это решается по дискриминанту 
вот формула D = b² - 4ac
где а - это то число где x²
где b - это то  число где x
где c - это то  число где нет x
Подставляем значения под формулу
D = 4² - 4 * 2 * b = 16 - 8b = 8b
дальше находим x1 и x2
по формуле 
х1= -b + квадратный корень из дискриминанта
                                  делим на 2а 
х2= -b - квадратный корень из дискриминанта
                                  делим на 2а 
Так же :
если дискриминант отрицательный то корней нет
если дискриминант равен нулю то корень только один
если дискриминант больше нуля то уравнение имеет два корня
