Electric Potential by Integrating Poisson's Equation

[appsci]

Hi
I need some help with understanding like i have this poisson's equation from which i have to determine the potential by integrating ofcourse using the boundary condition phi=0 at x=plus or minus L/2 and that differentiation of phi with x is zero at x=0.

I see that they have arrived at the equation
phi= 1/2 rho/epsilon* (square of L/2 - square of x)

I don't know how they got this.

Note: How can I type physics symbols here?

Thanks

Thanks. I will do so but can I know how to type equations or insert symbols over there.
