4s^(2)-4x+1

A circle S cuts three circles x^(2) + y^(2) - 4x - 2y + 4 = 0 , x^(2) + y^(2) - 2x - 4y + 1 = 0 " and " x^(2) + y^(2) + 4x + 2y + 1 = 0 orthogonally . Then the radius of S is

4x^(2) - 4x + 1 = ("__________")^(2)

solve the equations (i) x^2-2x-8 (ii) 4s^2-4s+1

The parabolas y^(2)=4x and x^(2)=4y divide the square region bounded by the lines x=4,y=4 and the coordinate axes.If S_(1),S_(2),S_(3) are the areas of these parts numbered from top to bottom,respectively, then S_(1):S_(2)-=1:1(b)S_(2):S_(3)-=1:2S_(1):S_(3)-=1:1(d)S_(1):(S_(1)+S_(2))=1:2

The parabolas y^(2)=4x,x^(2)=4y divide the square region bounded by the lines x = 4, y = 4 and the co-ordinate axes. If S_(1),S_(2),S_(3) are respectively the areas of these parts numbered from top to bottom then S_(1):S_(2):S_(3) is

If x^(4) -16x^(3) + 86x^(2) - 17x + 105 = 0 then s_(1), s_(2) , s_(3), s_(4) are
