回答1:

解:
60x-x^2-500=0
x^2-60x+500=0
(x-50)(x-10)=0
x-50=0或x-10=0
x=50或x=10

回答2:

60x -x²=500
x²-60x+500=0
(x-10)(x-50)=0
x=10 x=50

回答3:

x(60-x)=500
x²-60x+500=0
(x-10)(x-50)=0{运用的师资相乘法)
x=10,或x=50

回答4:

x(60-x)=500
60x-x^2=500
x^2-60x+500=0
(x-10)(x-50)=0
x=10或x=50

回答5:

x(60-x)=500
x²-60x+500=0
(x-10)(x-50)=0
x=10,x=50
