x^{2}-x-6=0 -x+3\gt 2x+1 ; line\:(1,\:2),\:(3,\:1) f(x)=x^3 ; prove\:\tan^2(x)-\sin^2(x)=\tan^2(x)\sin^2(x) \frac{d}{dx}(\frac{3x+9}{2-x}) (\sin^2(\theta))' \sin(120)

Rewrite 2x^ {2}-3x+1 as \left (2x^ {2}-2x\right)+\left (-x+1\right). Factor out 2x in the first and -1 in the second group. Factor out common term x-1 by using distributive property. If a line parallel to y=-7x+3 touches the parabola 2x^2-3x+2 in the point (x_0,y_0), what is the value of 4x_0+y_0?

可使用变换式 ax^ {2}+bx+c=a\left (x-x_ {1}\right)\left (x-x_ {2}\right) 对二次多项式进行因式分解，其中 x_ {1} 和 x_ {2} 是二次方程式 ax^ {2}+bx+c=0 的解。 形式为 ax^ {2}+bx+c=0 的所有方程式均可求解，方法是使用二次公式来求解: \frac {-b±\sqrt {b^ {2}-4ac}} {2a}。 此二次公式可得到两个解，一个是当 ± 取加号时的解，另一个是取减号时的解。 现在 ± 为加号时求公式 x=\frac {3±\sqrt {17}} {4} 的解。 将 \sqrt {17} 加上 3。 现在 ± 为减号时求公式 x=\frac {3±\sqrt {17}} {4} 的解。

令 $x^2$ 为 $y \ (y \ge 0)$,就变成了一个二次方程式,可以求出它的两个根 $y_1, y_2$。 二次次方程式的根可通过如下方式求出: $$x_{1,2} = \pm \sqrt {y_1}, \ \ \ x_{3,4} = \pm \sqrt {y_2}$$
