Homework Statement
[tex]\dot{x}=2x+5y+1, \dot{y}=-x+3y-4[/tex]
Homework Equations
The Attempt at a Solution
Well, if system was: [tex]\dot{x}=2x+5y, \dot{y}=-x+3y[/tex] we let a=2, b=5, c=-1, d=3.
Then p = a + d and q =ad - bc and we investigate [tex] p^2-4q[/tex]
Don't know what to do when [tex]\dot{x}=2x+5y+1, \dot{y}=-x+3y-4[/tex]
Thanks
