Homework Statement



Was just wondering how this equation:

[tex](k*16*10^(-6))/d^2=(k*16e-6)/(30-d)^2[/tex]

gets manipulated to produce this result

[tex]20(3-d)^2=d^2 [/tex]

[tex]d=2[/tex]

The Attempt at a Solution



I've tried manipulating it myself but it ends up with me spiraling off into pages of crap that is obviously wrong.

Are you sure you typed that in right?

Were you trying to say this?:
(k*16*10-6)/d2 = (k*16*10-6)/(30-d)2

If so, then first you would cancel the k expressions at the top, reciprocal both sides, expand and solve for d. However, I get a different result than what you give below.
