解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2:(2x+5)/(x
解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2
解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2
解方程:(2x+5)/(x+3)+(x+3)(2x+5)=2
:(2x+5)/(x+3)+(x+3)/(2x+5)=2
两边乘以(x+3)(2x+5)得
(2x+5)²+(x+3)²=2(x+3)(2x+5)
(2x+5)²-2(x+3)(2x+5)+(x+3)²=0
(2x+5-x-3)²=0
(x+2)²=0
∴x=-2
检验：x=-2是方程的解
:(2x+5)/(x+3)+(x+3)/(2x+5)=2
两边乘(x+3)(2x+5)得
(2x+5)²+(x+3)²=2(x+3)(2x+5)
(2x+5)²-2(x+3)(2x+5)+(x+3)²=0
(2x+5-x-3)²=0
(x+2)²=0
∴x=-2
