2y-4x^2+8=0

解答

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

解答

(h, k) = (0, - 4), p = \frac{1}{8}

求解步骤

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

将

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

改写为标准形式:

4 \cdot \frac{1}{8} (y - (- 4)) = (x - 0)^{2}

因此抛物线性质是:

(h, k) = (0, - 4), p = \frac{1}{8}

流行的例子

(y-7)^2+24(x+4)=0

(y - 7)^{2} + 24 (x + 4) = 0

(x+3)^2=-2(y-2)

(x + 3)^{2} = - 2 (y - 2)

(y-(6))^2=2(x-1)

(y - (6))^{2} = 2 (x - 1)

-8(x-5)=(y+1)^2

- 8 (x - 5) = (y + 1)^{2}

x - y^{2} + 2 = 0
