解 (3x^2+2x+1)/(x-1) =3x+1的x.
我们得到了这样的方程: ``` (3x^2 + 2x + 1) / (x - 1) = 3x + 1 ``` 为了解答 `x`,我们可以交乘去除分数: ``` (3x^2 + 2x + 1) = (x - 1) ((3x + 1) = 3x^2 - 2x - 1 ``` 现在我们有一个二次方程,我们可以简化通过结合类似的术语: `` 0 = 3x^2 - 5x - 2 `` ` ` 我们可以因数这个二次方程,得到: ``` 0 = (3x + 1) ((x - 2) `` ` 因此,解决方案是: `` 3x + 1 = 0 或 x - 2 ` ` ` ` ` ` ` -1/3 或 x = 3 ` ` ` ` ` x = 2 ` ` ` x = 2 ` ` ` ` ` x = 3 ` ` ` ` ` ` ` ` ` x = 2 ` ` ` ` ` ` x = 2 ` ` ` ` ` ` ` ` ` x = 2 ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ` ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒ ⌒
