∫sec⁡2x−2∫xsec⁡2x\displaystyle \int \sec ^2x - 2 \int x\sec ^2 x and you can do the second integral by parts.
Expand and use parts.
Remember sec⁡2x\sec^2 x integrates to tan⁡x\tan x
Use the integrate by parts rule:

Then remember sec2xsec^2 x integrates to tanxtanx

tan x =sin x/cos x and d(cos x)/dx=-sin x should help you avoid avoid parts
