Let's suppose we have a spring fixed to a wall, attached to a block and nothing is said about the forces acting on the block or spring but it's. It's known that if the block is displaced in the positive direction, the work done on the spring will be equal to (1/2)kx²$\frac12 kx^2$ and the work done by the spring will be (-1/2)kx²$-\frac12 kx^2$. How How can the work done be equal and opposite when to displace an object the forces required should be unequal.?

How can work done be equal and opposite when the forces are unequal and object travels the same distance
