Trying to solve a equation with its boundary conditions But an error message occurs in dsolve function??
Equation used : 1*D2y(x)+2*Dy(x)-3*y(x)=6 y(2)=4 y(0)=
Pls help me??

Preethika, I do not know how you implemented it, so here is one approach:
syms y(x)
Dy = diff(y);
D2y = diff(y,2);
% Define differential equation
my_DE = D2y + 2*Dy - 3*y == 6;
% Set initial conditions
y0 = y(0) == 0;
y2 = y(2) == 4;
% Solve differential equation and display
y_sol = dsolve(my_DE, y0, y2)
