i've been staring at these problems for at least an hour and still don't know where to start

can anyone give me some hints?

1.) integrate [(x^2)/(2+3x)^(1/2)] dx

2.) integrate [(x^2-25)^(1/2)/(x)] dx

i think this problem might be arcsin?? i don't know

these problems are either integration by parts (q*r-Sr*dq) or right triangles (trig)

thank you so much for any help!
