Hi matlondon,

The third line is like $\displaystyle {\color{red}a}b+{\color{red}a}$

Just factor out the, and you get a(b+1).*a*

Do you see it?

$\displaystyle {\color{red}x_2^{\frac{1}{2}}}\left[\frac{w_2}{w_1}\right]+{\color{red}x_2^{\frac{1}{2}}}$

$\displaystyle {\color{red}x_2^{\frac{1}{2}}}\left(\frac{w_2}{w_1 }+{\color{red}1}\right)$ - Apr 2nd 2010, 07:35 AMmatlondon
