(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

A force acting on an object moving along the x axis is given by F_{x}= 10x-2.0x^{2}N where x is in m. How much work is done by this force as the object moves from x = -1 to x= +6

Distance = 7 m

2. Relevant equations

Work = Force * Distance cosine theta

3. The attempt at a solution

The equation for force is already given so I found force by integrating the equation F_{x}= 10x-2.0x^{2}to get F_{x}= 10-4.0x then I substituted the x for 7 to get -18 Joules. The problem I have is that the answer I got isn't among the options.
