# Thread: help witha 2nd transpose plz

1. ## help witha 2nd transpose plz

help with this he coverted i pointed it out. can some one explain please.

thx you

2. Hi matlondon,

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

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

Do you see it?

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

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

yep i see that bit now, but how do you get w1+w2/w1 is the bit i fail to understand

I'll use a simpler example

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

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