Квадратные уравнения х(2х-3)=4х-3​

Ответ

Автор - Sleeplessness1

Ответ:

3 и 0,5

Пошаговое объяснение:

х(2х - 3) = 4х - 3

2х^2 - 3х = 4х - 3

2х^2 - 3х - 4х + 3 = 0

2х^2 - 7х + 3 = 0

D = b^2 - 4ac

D = (-7)^2 - 4 × 2 × 3 = 49 - 24 = 25

x = (- b ± √D)/2a

x = (-(-7) ± √25)/(2 * 2) = (7 ± 5)/4 = 3 и 0,5
