Question

how do you solve for x in the equation y=x+sqrt(x)

Answer 1

Start by doing something tricky.

Let x = k^2

Answer 2

Now re-write y in terms of k

Answer 3

\[y-x=x-x+\sqrt{x}\]
\[y-x=\sqrt{x}\]
\[(y-x)^2=(\sqrt{x})^2\]
\[(y-x)^2=x\]
see if you can do it from here

Answer 4

oh pooh. That's much less tricky.

Answer 5

but if you prefer an easy way ;)

Answer 6
