Answer 1

\[0.041=\frac{ x^2 }{ 0.1-x }\]

Answer 2

cross multiply first.

Answer 3

Quadratic:
x^2+0.041x-0.0041=0

Answer 4

^this quadratic is annoying

Answer 5

oh my... use quadratic formula?

Answer 6

\[\large \frac{-(0.041) \pm \sqrt{(0.041)^2-4(1)(-0.0041)}}{2(1)}\]

Answer 7

That might work.

Answer 8

simplification is too complicated :/

Answer 9

\[\large \frac{-0.041\pm \sqrt{0.001681 +0.0164}}{2}\] im sure you've got it from here,right? :D

Answer 10

wait i am doing

Answer 11

x= 0.046

Answer 12

-0.087

Answer 13

oh my ...it was a piece of cake!!!...my calculator was giving some crazy values of x

Answer 14

you're going to get two solutions once you solve \[\large \frac{-0.041- \sqrt{0.001681+0.0164}}{2}\] and \[\large \frac{-0.041+\sqrt{0.001681+0.0164}}{2}\]
