Someone plz help me to do this problem below. Thanks(adsbygoogle = window.adsbygoogle || []).push({});

1)a) Verify that y= e^(-x) and y= e^(2x)are both solutions of the differential equation y"-y'-2y=0

b) Factor the polynomial t^2-t-2. What connection do you see between the roots of this polynomial and the solutions of y"-y'-2y=0 ?---What does "roots" means in this case??..I don't understand.

*** t^2-t-2=(t-2)(t+1)
