解一道很简单的方程,只要结果!
(4-(根号下((5-x)^2-(3/5(5-x))^2)))^2+(3/5(5-x))^2=9

解一道很简单的方程,只要结果!(4-(根号下((5-x)^2-(3/5(5-x))^2)))^2+(3/5(5-x))^2=9
(4-(根号下((5-x)^2-(3/5(5-x))^2)))^2+(3/5(5-x))^2=9
(4-|5-x|根号下((25-9)/25))^2+(3/5(5-x))^2=9
设a=|5-x|
(4-4/5)a)^2+9/25*a^2=9
16+16/25*a^2-32/5a+9/25*a^2-9=0
5a^2-32a+35=0
(5a-7)(a-5)=0
a=7/5或5
x=32/5或18/5或0或10
