xx+12*12=yy(y-x=2)xx+12*12=yy(y-x=2)xx+12*12=yy(y-x=2)xx是x^2(x的平方)的意思吗?==>xx+12*12=yy==>x^2-y^2=-144

xx+12*12=yy(y-x=2)
xx+12*12=yy(y-x=2)

xx+12*12=yy(y-x=2)
xx是x^2(x的平方)的意思吗?
==>xx+12*12=yy
==>x^2-y^2=-144
==>(x+y)(x-y)=-144
==>x+y=-144/(x-y)=72
==>x=35,y=37

X=136
Y=138

(y-x)^2=4
yy-2xy+xx=4
xx-yy=-12*12
2xx-2xy=-140
x*(x-y)=-70
x=35
y=37

xx+12*12=yy(y-x=2) 已知2x=3y,求xy/xx+yy-yy/xx-yy的值 (x-y)(x+y)(xx-yy)=? xx+2x+yy+6y+10=0求xx+yy的值已知xx+yy+4x-6y+13=0,求（xx-2x）/xx+3yy的值. matlab程序如下：为什么提示运行出错?x= 0:0.01:20;y= 0:0.01:15;[xx,yy]=meshgrid(x,y,'r');q1=1./((yy-10).^2+(xx-4).^2+9);q2=1./((yy-10).^2+(xx-8).^2+9);q3=1./((yy-10).^2+(xx-12).^2+9);q4=1./((yy-10).^2+(xx-16).^2+9);q5=1./((yy-5).^2+(xx-4) 一下matlab程序运行有误,请问哪里有错,x= 0:0.01:20;y= 0:0.01:15;[xx,yy]=meshgrid(x,y,'r');q1=1./((yy-10).^2+(xx-4).^2+9);q2=1./((yy-10).^2+(xx-8).^2+9);q3=1./((yy-10).^2+(xx-12).^2+9);q4=1./((yy-10).^2+(xx-16).^2+9);q5=1./((yy-5).^2+(xx-4 已知x-y=2,（xx）-（yy）=12,求x与y的值已知x(x-1)-(xx-y)=-3求xx+yy-2xy 已知x（x+1)-(xx+y)=3,求(xx+yy)/2-xy的值 x(x+1)-(xx+y)=-3,求(xx+yy)/2-xy的值若xx+yy-2x-6y+10=0,求分式（xx-yy）/xy的值. X-Y=4,xy=12则xx+YY的值若xx-2x+yy+6y+10=0 求xx-yyy的值若xx-2x+yy+6y+10=0 求xx-yyy的值已知x,y是实数,且适合方程(xx+xy-12)(xx+xy-12)+(xy-2yy-1)(xy-2yy-1)=0求x,y的值已知：xx+yy-8x+12y+52=0,求：x/y-y/x=多少 x-y/x+y=2,则xx+2xy+yy/4xy=?
