Question

Differentiate

H(u) = (u-(square root of u)) (u+(square root of u))

Answer 1

\[H(u)=(u-\sqrt{u})(u+\sqrt{u})\]

Answer 2

answer should be 2u-1 but explain a little please?

Answer 3

does i help to know that
\[(u+\sqrt{u})(u-\sqrt{u})=u^2-u\]?

Answer 4

wait did you just combined them? i know then you take 2 down and subtract one to power

Answer 5

and u ^1-1 so it will be just 1

Answer 6

yes i get it now i was just lost that should i combine them! thank you
