y^{''}-7y^'-4y=0

y^{^{''}} - 7 y^{^{'}} - 4 y = 0

y = c_{1} e^{\frac{( 7 + 65 ) t}{2}} + c_{2} e^{\frac{( 7 - 65 ) t}{2}}

Solution steps

y^{''} (t) - 7 y^{'} (t) - 4 y = 0

Solve linear ODE:

y = c_{1} e^{\frac{( 7 + 65 ) t}{2}} + c_{2} e^{\frac{( 7 - 65 ) t}{2}}

y = c_{1} e^{\frac{( 7 + 65 ) t}{2}} + c_{2} e^{\frac{( 7 - 65 ) t}{2}}
