Num=input()
Num=Num.split()
judge=int(Num[1])**2-4*int(Num[0])*int(Num[2])
if judge>0:
    print(f"Two different roots x1={int((-int(Num[1])+judge**(1/2))//2*int(Num[0]))} , x2={int((-int(Num[1])-judge**(1/2))//2*int(Num[0]))}")
elif judge==0:
    print(f"Two same roots x={-int(Num[1])//2*int(Num[0])}")
else:
    print("No real root")
請問是哪裡出錯了

2*int(Num[0])

要括號
