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方程的。

But on the third, a type to which it is ideally suited (quadratic unconstrained binary optimisation, since you ask), D-Wave's machine dominated, racing through the job around 3,600 times faster than the classical hardware.

但到了第三个目（如果你一定要是什么的话也不妨告诉你：无约束二进制最优化），D-ware的机器表现得更好，比一般硬件配置的电脑要快约3600倍。

So, if you move all the terms over to one side, you'd put the quadratics into a form that can be factored, allowing that side of the equation to equal zero.

那么，将所有项移至等式的一边，就可以对这个二次方程因式分，等式的另一边自为零。

That question about the plots of land can be written as one of the first equations with unknowns you probably ever heard of, the quadratic equation.

关于土地的可以写成最早的未知数方程之一，你可能听说过，二次方程。

I was able to reduce what I had to find from an eighth-degree polynomial to a quadratic, and from the quadratic, the golden ratio fell out.

我可以把我的答案从八次方多项式简化成二次方程，后从二次方程中得出黄金分割率。

(Laughter) finding imaginary solutions to quadratic equations.

（笑声）寻找二次方程的虚。

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

由于二次公式的工作方式， 我们将得到 2 个可能的答案。

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

它被称为AQUAL理论，全称是二次拉格朗日。

Which you probably recognize as a quadratic equation.

这你可能认出是一个二次方程。

You know, fourth order quadratic synthetic division.

你知道，四阶二次成除法。

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。

And this is where a teacher will put up a method on the board, you know, maybe quadratic equations, and then students will memorize the method and then reproduce it as quickly and as accurately as possible.

这时， 老师会在黑板上展示一种方法，比如二次方程，后学生们会记住这种方法， 并尽可能快速且准确地再现出来。

School can teach your kids a lot of important things like the structure of a cell or the quadratic equation.

学校能教会孩子们许多重要知识，比如细胞结构或二次方程。

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 的平方，某种二次形式。

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

例如，第一节课将讲二次方程公式的简化版本。

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

如果你考虑回报方程，它是 1 加 r 的 n 次方，n 是二次方。

Quadratic funding is basically a crowdfunding campaign, but it's not like a Patreon where creators sell subscriptions.

二次方融资基本上是一种众筹活动，但它不像 Patreon 那样创作者出售订阅服务。

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

但“这个二次方程”会让课堂上的人不知所措，让演讲厅的人也不以为。

(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。
