## Homework Statement

Is it possible to solve this system of equations using matrices?

x^2 + y^2 = 42

x+3y+2y^2=6

## Homework Equations

## The Attempt at a Solution

I solved the system of equations using the following MATLAB code. I'm kind of confused by the results. Are there two x values and two y values? I don't know how to interpret what it says x and y are equal to. Thanks in advance.

Code:

```
>>one=sym('x^2+y^2-42');
two=sym('x+3*y+2*y^2-6');
[x,y]=solve(one,two)
x =
