    Hi matlondon,

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

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

    Do you see it?

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


    {\color{red}x_2^{\frac{1}{2}}}\left(\frac{w_2}{w_1  }+{\color{red}1}\right)

    I'll use a simpler example

    \frac{a}{b}+1=\frac{a}{b}+\frac{b}{b}=\frac{a+b}{b  }


    You see, you have to use the common denominator and make the 1 into the fraction \frac{b}{b}
