(3-h)^2+(5-k)^2=r^2

解

(3 - h)^{2} + (5 - k)^{2} = r^{2}

r = h^{2} - 6 h + k^{2} + 34 - 10 k, r = - h^{2} - 6 h + k^{2} + 34 - 10 k

解答ステップ

(3 - h)^{2} + (5 - k)^{2} = r^{2}

辺を交換する

r^{2} = (3 - h)^{2} + (5 - k)^{2}

簡素化

(3 - h)^{2} + (5 - k)^{2} : h^{2} - 6 h + k^{2} + 34 - 10 k

x^{2} = f (a)

の場合, 解は

x = f (a), - f (a)

r = h^{2} - 6 h + k^{2} + 34 - 10 k, r = - h^{2} - 6 h + k^{2} + 34 - 10 k
