anonymous 4 years ago help in this prob..i am typing it

1. anonymous

$\sqrt{2ab-ax-bx-2\sqrt{ab(ax-bx+x ^{2)}}}$

2. anonymous

what are we supposed to do with this ?

3. anonymous

the question is what are the roots ?

4. anonymous

$$x$$ is the variable isn't ?

5. anonymous

I don't think so.

6. anonymous

Anyways the roots are :$$\left\{\left\{x = \frac{2 \left(2 a^2 b-\sqrt{3 a^4 b^2+2 a^3 b^3-a^2 b^4}\right)}{a^2-2 a b+b^2}\right\},\left\{x= \frac{2 \left(2 a^2 b+\sqrt{3 a^4 b^2+2 a^3 b^3-a^2 b^4}\right)}{a^2-2 a b+b^2}\right\}\right\}$$

How can I solve it ? Put $$\sqrt{2ab-ax-bx-2\sqrt{ab(ax-bx+x ^{2)}}} =0$$ square both sides then reduce it to quadratic form,, after that ...

ok,i got it..thanks a lot
