4x+2y^2-6y=9

解

4 x + 2 y^{2} - 6 y = 9

(h, k) = (\frac{27}{8}, \frac{3}{2}), p = - \frac{1}{2}

解答ステップ

4 x + 2 y^{2} - 6 y = 9

4 x + 2 y^{2} - 6 y = 9

を標準的な形式で書き換える

4 (- \frac{1}{2}) (x - \frac{27}{8}) = (y - \frac{3}{2})^{2}

ゆえに放物線の特性は:

(h, k) = (\frac{27}{8}, \frac{3}{2}), p = - \frac{1}{2}
