Hi all! My problem concerns the simple differential equation:

I integrated four times and I ended up with this general solution (cconstant):

I'd assume this is the right solution. I looked up the answer afterwards and I found that the textbook wrote the solution as follows:

Are these solutions the same? How would I simplify my answer to get the textbook's answer? Just looking to clarify my solution here.

(Not sure if this belongs in the Calculus forum or the Differential Equations forum. I apologize greatly if I chose the wrong forum to post this question in.)
