经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0的交点且经过原点的圆的方程?经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0
经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0的交点且经过原点的圆的方程?
经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0的交点且经过原点的圆的方程?
经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0的交点且经过原点的圆的方程?
设圆系方程:(4x²+4y²+3x+y-8)+λ(3x²+3y²-2x+4y-10)=0
将点(0,0)代入上式,
得 -8+(-10)λ=0
解得 λ=-4/5
所以所求的圆方程:(4x²+4y²+3x+y-8)-4/5 (3x²+3y²-2x+4y-10)=0
整理得:8x²+8y²+23x-11y=0
答案:8x²+8y²+23x-11y=0
经过圆4x^2+4y^2+3x+y-8=0与圆3x^2+3y^2-2x+4y-10=0的交点且经过原点的圆的方程?
经过圆4x²+4y²+3x+y-8=0与圆3x²+3y²-2x+4y-10=0的交点且经过原点的圆的方程是
(x-y) (x-2y)+(x+2y) (x-3y)-2(x-3y) (x-4y)=
(4x-2y-z)-{5x[8y-2y-(x+y)]-x+(3y-10z)]=? kuaihuajian
9y=3x-(x-1),4(x+y)-(2x+4)=8y
已知实数x.y满足根号(x+y-8)+根号(8-x-y)=根号(3x-y-4)+根号(x-2y+7),求x,y
81/8*(-x-y)^6*(x-y)^3*4/9(x+y)^4*(y-x)^2
4x-3y/x-2y÷6y-8x/y-2x
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
2(x+y)-3(x-y)=3 ,4(x+y)+3(x-y)=15
3(x+y)+2(x-y)=36 4(x+y)-5(x-y)=2
(x+y)/2- x-y/2=6 3(x+y)=4(x-y)
x+y/3+x-y/2=6 4(x+y)-2(x-y)=40
x+y/2+x-y/3=6,4(x+y)-3(x-y)=-20
{(x+y)/2+(x-y)/3=6 4(x+y)-3(x-y)=-20
4(x+y)-3(x-y)=-20,2/x+y+3/x-y=6
3(x+y)-2(x-y)=11 4(x+y)+3(x-y)=9
4(x-y)-3(x-y)=9 5(x-y)+2(x-y)=11
