i need to find the antiderivative of 2x+5/sqareroot of x^2+5x+7 and im really stuck

OpenStudy (anonymous):

u substitution. klet u = x^2 + 5x + 7 then du = (2x + 5)dx

OpenStudy (anonymous):

so it would be u\u^1/2? and then i derive from there?

OpenStudy (anonymous):

i think i got it thanks

OpenStudy (anonymous):

no it would be du/u^1.2 or u^(-1/2)du. integrate from there.
