四、計算題答案及解題過程：

1.計算導數：

$f(x)=\sqrt{x^3-6x+9}$

使用鏈式法則，設$u=x^3-6x+9$，則$f(x)=\sqrt{u}$。

$f'(x)=\frac{1}{2\sqrt{u}}\cdotu'$

$u'=3x^2-6$

$f'(x)=\frac{3x^2-6}{2\sqrt{x^3-6x+9}}$

2.解一元二次方程：

$x^2-5x+6=0$

使用因式分解法：

$(x-2)(x-3)=0$

解得：$x=2$或$x=3$

3.計算定積分：

$\int_0^1(2x^3-3x^2+4x)\,dx$

分別積分各項：

$\int_0^12x^3\,dx=\frac{2}{4}x^4\bigg|_0^1=\frac{1}{2}$

$\int_0^1-3x^2\,dx=-\frac{3}{3}x^3\bigg|_0^1=-1$

$\int_0^14x\,dx=\frac{4}{2}x^2\bigg|_0^1
