代数示例

y = a {(x - h)}^{2} + k

$y = a {(x - h)}^{2} + k$

解题步骤 1

将方程重写为

a {(x - h)}^{2} + k = y

$a {(x - h)}^{2} + k = y$ 。

a {(x - h)}^{2} + k = y

$a {(x - h)}^{2} + k = y$

解题步骤 2

从等式两边同时减去

k

$k$ 。

a {(x - h)}^{2} = y - k

$a {(x - h)}^{2} = y - k$

[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]

$[\begin{array}{c} x^{2} & \frac{1}{2} \\ \sqrt{π} & \int x d x \end{array}]$
