U do not need to write down the steps.

6 cosh x = 6/5 x^5 + 3x^4 + 8x³ + 24x² + 96x + C
If C is not given, then x can be any real number. That's all.

What a strange question! I assume you can work out the integral -- except that it's indefinite, and there's no information to determine the arbitrary constant. So do we leave it out, assume it's 0?
Then you put =6cosh(a1) in the cell b1 of a spreadsheet, in cell c1 put the formula for calculating the polyomial ((6/5)x^5 + etc), copy these formulas down a few rows, and put values in column A until you get equal values of the two functions. But use your time rather than mine to do it!
Then again, if you email h_chalker@yahoo.com.au in about20 hours time, curiosity will probably have compelled me to find an answer.

FWIW I concur with Hy and falzoon. It's a weird question. But, making Hy's assumption, I ripped out a few lines of code and got x = 0.061635 which is real close to falzoons answer.

I'm glad you don't want me to write down the steps.
x = 0.061648677766605, which is about the best I can do.
This gives an answer of 6.01140528993168
for both expressions.
