已知(a^2+1)(b^2+1)-6ab+3=0,求2a^2b+2ab^2D的值.已知(a^2+1)(b^2+1)-6ab+3=0,求2a^2b+2ab^2D的值.已知(a^2+1)(b^2+1)-6

已知(a^2+1)(b^2+1)-6ab+3=0,求2a^2b+2ab^2D的值.
已知(a^2+1)(b^2+1)-6ab+3=0,求2a^2b+2ab^2D的值.

已知(a^2+1)(b^2+1)-6ab+3=0,求2a^2b+2ab^2D的值.
已知(a^2+1)(b^2+1)-6ab+3=0,
a²b²+a²+b²+1-6ab+3=0;
a²b²-4ab+4+a²+b²-2ab=0;
(ab-2)²+(a-b)²=0;
ab=2;
a-b=0;
a=b;
a=b=±√2;
求2a^2b+2ab^2
=2ab(a+b)
=2×2×(±2√2)
=±8√2;
