Can you please help me with part a? Thank you!

(10%) Problem 4: The force required to compress a non-standard spring as a function of displacement from equilibrium x is given by the equation F(x) = ax2 - bx, where a = 75 N/m , b = 12 N/m, and the positive x direction is in the compression direction of the spring. 33% Part (a) Write a general equation in terms of the given variables for the work required to compress this spring from equilibrium to any point xp.
