It looks like there's been an error whilst giving you this question, it's quite tedious and annoying. There's the hyperbolic trig sub as the above user has pointed out or x↦25tanx which gets you 25∫sec3xdx where a standard reduction formulae gets you where you want to go.
thank you! i don't think i've been taught trigonometric substitution, yet this is a question in the AQA fp2 text book so i'm guessing i have to learn it.
yes. i know up to integrals which integrate to inverse hyperbolic functions but i'm pretty sure i don't know how to substitute trig functions in to integrate

Well there is not a specific section on integration using hyperbolic functions - you have simply been made aware of the hyperbolic functions in FP2 - tools which can be used for integration.

I'm fairly sure you should... it's on Edexcel FP2 that's for sure. Do you have a link to the FP2 AQA specification?
Yeah, that's what I meant. I mashed all my learning of C1-4 together and mashed FP2-3 together so I don't know what's in one and not the other. Thanks.
