Question

3y^2-5y+2=0 Me ajudem ??

Answer 1

3y²-5y+2=0
∆= b²-4ac
∆= 25-4x3x2
∆= 25-24
∆=1

x=-b +-√∆
2a

x= 5 +-√1
6

x'= 5+1 = 6 = 1
6 6

x"= 5-1 = 4 ÷2= 2
6 6 ÷2 3

Answer 2

A=3 B=-5 C= 2

∆=b² - 4 * a * c

∆=-(-5)² - 4 * 3 * 2

∆= 25-24

∆ = 1

x=(-b+-√∆) / 2*a

x=(-(-5)+-√1) / 2*3

x=(5+-1) / 6

x' = (5 + 1) / 6

x' = 1

x" = (5 - 1) / 6

x" = 4/6=2/3

s={ 2/3 , 1 }
