solve解显示root(一个方程)，怎么显示出数值解？
请参考以下Matlab代码。
注意应用solve（）函数的格式。例如solve(f(x)0,x)可以简写成以下形式：solve(f(x)) 运行如下Matlab代码： syms x; solve(det([5*x 2
1; -1 4*x
2; 2 -3 10*x])) eval(ans) 运行结果如下： ans -0.2147 0.1074 0.4946i 0.1074 - 0.4946i

I am writing to express/air dissatisfaction/disappointment/concern regarding accommodation. I would prefer to move into a single room next semester， as I find the present sharing arrangement inconvenient.
I must explain that the reason for my dissatisfaction is my roommate‘s inconsiderate behavior. For one thing， his friends are constantly visiting him; for another， he regularly holds noisy parties.
To solve this problem/surmount this difficulty/improve this situation/crack this hard nut， I hope to draw the attention of the authorities concerned. I am sure you will aGREe that the only solution for me is to move into a room of my own. Therefore， I would be grateful if you could find a single room for me， preferably not in the same building but as near to the college campus as possible.
Yours sincerely，
Li Ming
