a2+b2-2a+6b+10=0大家帮帮忙a2+b2-2a+6b+10=0大家帮帮忙a2+b2-2a+6b+10=0大家帮帮忙(a2-2a+1)+(b2+6b+9)=0(a-1)2+(b+3)2=0a

a2+b2-2a+6b+10=0大家帮帮忙
a2+b2-2a+6b+10=0大家帮帮忙

a2+b2-2a+6b+10=0大家帮帮忙
(a2-2a+1) + (b2+6b+9) = 0
(a-1)2 + (b+3)2 = 0

a^2 + b^2 - 2a + 6b + 10 ................= 0
= (a^2 - 2a + ) + (b^2 + 6b + 9)
= (a - 1)^2 + (b + 3)^2
= 0
p平方数不小于 0,最小是等于 0
a - 1 = 0 ..... a = 1
b + 3 = 0 ..... b = -2

a=1
b=-3
