x2-﹙x-1﹚*x=3.x2-﹙x-1﹚*x=3.x2-﹙x-1﹚*x=3.x2-﹙x-1﹚*x=3.5x²-x²+x=3.5x=3.5
x2-﹙x-1﹚*x=3.
x2-﹙x-1﹚*x=3.
x2-﹙x-1﹚*x=3.
x2-﹙x-1﹚*x=3.5
x²-x²+x=3.5
x=3.5
x2-﹙x-1﹚*x=3.
①x/(x2-1) ·(x2+x)/x2其中x=2 ②(x2-1)/(x2+4x+4)÷(x+1).(x+2﹚/﹙1-x﹚其中x=-3
已知x/﹙x2-3x+1﹚=2,则x2/x的4次方+x2+1=
7/x2+x+1/x2-x=6/x2-1
3/x2 -3x+2-1/x-2=1/x2 -x+4/x2 -2x
x2-3x+1=0 x2/(x4-x2+1)
x2-5x+1=0则x2+x2/1
y=x+√(1-x2) y2=x2+(1-x2)+2x√(1-x2)
y=(x-1/X)(X2-1/X2)的导数,
x+1/x=3,求x2/x4+x2+1
2( x2 +1/x2) - 9( x + 1/x) + 14 =
解方程(x2+x+1)(x2+x+12)=42
因式分解(x2+x+1)(x2+x+2)-12=
解方程(x2+x)(x2+x-2)=-1
x2+x-6/(x2+x)+1=0怎么做
解方程x2-6/ x2-x=x-1
解方程:x2+1+x=6/x+x2
函数y=(x2-x)/(x2-x+1)的值域
