x^2-4x+y^2-4x-8=0

解

x^{2} - 4 x + y^{2} - 4 x - 8 = 0

解

(a, b) = (4, 0), r = 26

解答ステップ

x^{2} - 4 x + y^{2} - 4 x - 8 = 0

x^{2} - 4 x + y^{2} - 4 x - 8 = 0

を標準的な円のequationの形式で書き換える

(x - 4)^{2} + (y - 0)^{2} = (26)^{2}

ゆえに円の特性は:

(a, b) = (4, 0), r = 26

x^{2} + y^{2} + 5 x - y = 0

(x-1/2)^2+(y-1)^2=9

(x - \frac{1}{2})^{2} + (y - 1)^{2} = 9

(x-1/2)^2+(y+9)^2=64

(x - \frac{1}{2})^{2} + (y + 9)^{2} = 64

(x+3/2)^2+(y-1/2)^2=25

(x + \frac{3}{2})^{2} + (y - \frac{1}{2})^{2} = 25

x^2+y^2+8x-2y-17=0

x^{2} + y^{2} + 8 x - 2 y - 17 = 0
