已知a²+b²-10a-6b+34=0 求（a-b/a+b)²÷a²-b²/abXa²+2ab²/a²-ab
已知a²+b²-10a-6b+34=0 求（a-b/a+b)²÷a²-b²/abXa²+2ab²/a²-ab
已知a²+b²-10a-6b+34=0 求（a-b/a+b)²÷a²-b²/abXa²+2ab²/a²-ab
∵a^2+b^2-10a-6b+34=0
∴a^2-10a+25+b^2-6b+9=0
∴(a-5)^2+(b-3)^2=0
∵(a-5)^2≥0,(b-3)^2≥0
∴(a-5)^2=0,(b-3)^2=0
∴a=5,b=3
a²+b²-10a-6b+34=0
(a-5)^2+(b-3)^2=0
a=5
b=3
（a-b/a+b)²÷a²-b²/abXa²+2ab²/a²-ab
