Such as the email I sent yesterday was related to quadratic equation.

比如我昨天发的邮件是关于一个二次的问题。

(Laughter) finding imaginary solutions to quadratic equations.

（笑声）寻找二次的虚解。

And we end up with this. Which you probably recognize as a quadratic equation.

我们最终得到了这个。 可能认为这是一个二次。

To solve the quadratic equation we have to use the quadratic formula.

要求解二次， 我们必须使用二次公式。

It's called AQUAL, which stands for A Quadratic Lagrangian.

它被为AQUAL理论，全是二次拉格朗日。

Which you probably recognize as a quadratic equation.

这可能认出是一个二次。

You know, fourth order quadratic synthetic division.

，四阶二次合成除法。

(bell rings) - So that's our refresher on the quadratic formula.

（铃响）- 这就是我们对二次公式的复习。

As if my fellow mathlete here would have any questions about the quadratic formula.

- 好像我的数学家同学会对二次公式有任何疑问。

Not even a quadratic basis to work with here.

甚至找不出两个相同的动作。

Well, it turns out this is e to the minus mu squared, some quadratic form.

嗯，事实证明这是 e 到负 mu 的平，某种二次形式。

Thing, e to the minus quadratic form, is Gaussian.

事物, e 到负二次形式, 是高斯。

So the quadratic term is multiplied by the inverse variance.

因此, 二次项乘以逆差。

And because of the way the quadratic formula works, we'll get 2 possible answers.

由于二次公式的工作式， 我们将得到 2 个可能的答案。

Quadratic funding isn't just for downtowns that want to revitalize after a pandemic.

二次融资不仅仅适用于那些希望在疫情后振兴的市中心。

But " solve this quadratic equation" would leave the classroom nonplussed and the lecture theatre unimpressed.

但“解这个二次”会让课堂上的人不所措，让演讲厅的人也不以为然。

This is what we call a preference map from a recent quadratic funding campaign that we've run.

这是我们之为最近进行的二次融资活动中的一种偏好地图。

For example, the very first lesson is going to be on a simpler version of the quadratic formula.

例如，第一节课将讲解二次公式的简化版本。

If you think of the equation for returns, it's 1 plus r to the n, n is quadratic.

如果考虑回报，它是 1 加 r 的 n 次，n 是二次。

Of mu given x bar is equal to quadratic terms multiplier inverted.

mu 给定 x bar 等于倒置的二次项乘数。
