    Take the definite integral of one and subtract out the definite integral of the other.

    Set the equations equal to learn where they intersect and which is above the other, then take the definite integral of the lower function subtracted from the higher function, between the limits that you found.

    Graphing is a good quick way to learn the limits of integration and which equation is larger.

    fine the points of interception, those will be your bounds of integration.

    By looking at that graph you can see that the two functions intersect at x=0 and x=5, so those will be your limits of integration. They also show you that the linear function is above the quadratic function, so you subtract the quadratic function from the linear function, then integrate it from 0 to 5.
