(35S) Quick integration

[Liamtoh Resu]

This inquiry concerns the calculus of integrating the sqrt(1+4x2) function.

I have elementry calculus skills.

I have run the function through the hp prime calculator in cas mode, xcas,
and two versions of maple (version 12 and old win 3.1 version).

I get results containing natural logs in on the prime. and I get results containing
arcsinh in Maple.

I have done the math calculations on the prime, dm 15L, free42, hp15c android app,
hp 35s, hp50g, and some others calcs. I get the same numerical answer,
eg 1.47894285....

Can someone walk me througj the symbolic calculation of the function?

Thanks
