(d^2y)/(dx^2)+14(dy)/(dx)+49y=0

\frac{d ^{2} y}{d x ^{2}} + 14 \frac{d y}{d x} + 49 y = 0

y = c_{1} e^{- 7 x} + c_{2} x e^{- 7 x}

Solution steps

\frac{d ^{2} y}{d x ^{2}} + 14 \frac{d y}{d x} + 49 y = 0

Solve linear ODE:

y = c_{1} e^{- 7 x} + c_{2} x e^{- 7 x}

y = c_{1} e^{- 7 x} + c_{2} x e^{- 7 x}
