And he inherited al - Khwarizmi's solution to quadratic equation.───同时,他继承了前辈花拉子米关于一元二次方程的解法.

In high-school algebra, you learned that the standard quadratic equation.───在高中代数学里，你学习了标准二次方程序。

Usually, x is a quadratic equation , x has two different solutions.───二次方程式通常都有两个不同的解.

The child then knows how to solve a quadratic equation.───于是学生就会解二次方程了.

Theoretically speaking, it is a rather-clearly discussed subject to standardize the quadratic equation into the normal forms by spinning the coordinate axis so as to approach the shapes of its curves.───从理论上讲，通过坐标轴旋转将二次方程化简为规范形式，从而讨论其曲线的形状，这已是讨论得相当明了的课题。
