Ok Verify so when x=0 and x=2 we know that the curve will have a y-value of zero at that point. thus those are the limits/whatever u call it u put onto the integrate symbol.
^2 dx=\int_{0}^{2}kx(4-4x+x^2)dx=\int_{0}^{2}4kx -4kx^2 +kx^3 dx=1 )
From there it is simple integration and then u sub in x=2 and x=0. I think this should be right anyways...

That's right - but leave the k outside; much easier.Ok Verify so when x=0 and x=2 we know that the curve will have a y-value of zero at that point. thus those are the limits/whatever u call it u put onto the integrate symbol.
