如图,求化简过程:(x1+x2)/2+(ax1²-1+ax2²-1)/2=0,x1x2=1-a/a²如图,求化简过程:(x1+x2)/2+(ax1²-1+ax2

如图,求化简过程:(x1+x2)/2+(ax1²-1+ax2²-1)/2=0,x1x2=1-a/a²
如图,求化简过程:(x1+x2)/2+(ax1²-1+ax2²-1)/2=0,x1x2=1-a/a²

如图,求化简过程:(x1+x2)/2+(ax1²-1+ax2²-1)/2=0,x1x2=1-a/a²
上面还有一个x1+x2=1/a
:(x1+x2)/2+(ax1²-1+ax2²-1)/2=0
x1+x2+a(x1²+x2²)-2=0
1/a+a[(x1+x2)²-2x1x2]-2=0
1/a+a(1/a²-2x1x2)-2=0
1/a+1/a-2a(x1x2)-2=0
2a(x1x2)=2-(2/a)
x1x2=(2a-2)/(2a²)
x1x2=(a-1)/a²
