Help with Integration of expression

[Brinkley23]

Hi All,

I've made an attempt at solving the following equation, Im hoping I have understood the rules enough to answer correctly apart from the second term:

y= 'integral symbol'(4x² + x^-2 + 4)dx

My workings out so far are attached.

I'm never confident when having to multiply or divide negatives.

Thanks

You've got everything correct. [math]\dfrac{x^{-1} }{-1} = -x^{-1} = - \dfrac{1}{x}[/math]

Thanks for replying Dan,

Can you take a look at what Ive wrote as my final solution as Im not sure If how I've written it is now reading correct?
