(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

From the taylor series we can replace [tex]x =x_{0} + h[/tex]

but how does

[tex]\delta f = f(x_{0} + h, y_{0} + k) - f(x_{0},y_{0})[/tex]

become

[tex]\delta f = hf(x_{0}, y_{0}) + kf(x_{0}, y_{0})[/tex]

I can see the first step, but how do you get it to the second?
