## Homework Statement

A particle that can move along the x-axis experiences an interaction force Fx=(3x

^{2}−5x) N where x is in m. Find an expression for the system's potential energy. Express your answer in terms of the variables x and the constant of integration C, where C is in joules.

## Homework Equations

I used simple integration rules to solve this problem.

## The Attempt at a Solution

∫(3x

^{2}−5x) = x

^{3}-5/2 x

^{2}+C

I put this answer and the feedback said to "check your signs". I was confident that the above was right, so where is my mistake in the sign?
