If the point P(x, y) be equidistant from the points (a+b, b-a) and (a-b, a + b) , prove that (a-b)/(a+b) = (x-y)/(x+y) .

If the point P(x, y) be equidistant from the points (a+b, b-a) and (a-b, a + b) , prove that (a-b)/(a+b) = (x-y)/(x+y) .

2(x/a)+(y/b)=2; (x/a)-(y/b)=4

If (x/a) + (y/b) = 3 and (x/b)-(y/a) = 9, then what is the value of x/y? यदि (x/a) + (y/b) = 3 तथा (x/b)-(y/a) = 9 है, तो x/y का मान क्या है? ,

2(a x-b y)+(a+4b)=0 , 2(b x+a y)+(b-4a)=0

If A=("x y"),B=((a,h),(h,b)),C=((x),(y)) then ABC=

a, b, x are in AP, a, b, y are in GP and a, b, z are in HP, then prove that 4z(x-y)(y-z)=y(x-z)^2 .
