# matlab find roots of symbolic polynomial

To find the roots of a symbolic polynomial in MATLAB, you can use the `solve`

function. Here's an example of how to use it:

```
syms x
eqn = x^2 - 4*x + 3 == 0;
sol = solve(eqn, x);
```

In this example, we define a symbolic variable `x`

using the `syms`

function. Then, we define the polynomial equation `eqn`

using the symbolic variable `x`

. Finally, we use the `solve`

function to find the roots of the equation and store them in the variable `sol`

.

You can replace the equation `x^2 - 4*x + 3 == 0`

with your own polynomial equation. The `solve`

function will return the roots of the equation as a symbolic expression or a numeric value, depending on the input.

Please note that the `solve`

function may not be able to find symbolic solutions for all polynomial equations. In such cases, it may return numeric approximations instead.
