I'm not sure how to factorise this after differentiating - hopefully I've done this right.....
Q:Find the exact gradient of the tangent to the curve y=x(2x+5)^1/2 at the point where x=1...
I've differentiated to (2x+5)^1/2 + x(2x+5)^-1/2.... I think the x is wrong?
Thanks for your help in advance...![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
