Question

8х-12х+4=0 срочно нужно

Answer 1

8х - 12х + 4 = 0
- 4х = - 4
Х = ( - 4 ) : ( - 4 )
Х = 1

Answer 2

1)8х - 12х + 4 = 0
   -4х = -4
    х = 1

2)8х² - 12х + 4 = 0
D = 16
х1 = (-b-√D)/2a = (12 - 4)/2*8 = 8/16=0.5
х1 = 0,5
x2 = (-b +√D)/2a = (12+4)/16=16/16=1
х2 = 1

Answer 3

как нашли х1 и х2
