ah²+3=3=5/3,a(10-h)²+3=0求高人解题过程是ah²+3=5/3,a(10-h)²+3=0(打错了)ah²+3=3=5/3,a(10
ah²+3=3=5/3 ,a(10-h)²+3=0求高人解题过程是ah²+3=5/3 ,a(10-h)²+3=0(打错了)
ah²+3=3=5/3 ,a(10-h)²+3=0求高人解题过程
是ah²+3=5/3 ,a(10-h)²+3=0(打错了)
ah²+3=3=5/3 ,a(10-h)²+3=0求高人解题过程是ah²+3=5/3 ,a(10-h)²+3=0(打错了)
ah²+3=5/3 得 a=-4/3h^2 代入
a(10-h)²+3=0 得
(10-h)^2=(3h/2)^2
得10-h=3h/2 或 10-h=-3h/2
得 h=4或h=-20
a=-1/12,或 a=-1/300
