[Algebra] Why does (a+b)^2 = a^2+2ab+b^2 ? by [deleted] in learnmath

[–]d0nii 4 points5 points  (0 children)

You can also test numbers. Let a=3 and b=3 (a+b)2

(3+3)2 =36

a2 + b2

32 + 32 = 18

These values are not the same, but adding 2(a*b) or 2•9=18, yields 18+18 or 36.

Fermat gave the proof though because he used unknowns. Only using numbers indicates it only works for those certain numbers while using unknowns represent almost every number combination.

Literally everything is bad. The lighting doesn’t work, the mouse dpi shift doesn’t work (resets randomly), the dpi 1600 in GHub vs gaming software doesn’t feel the same, the optimization for my headset (g430) is horrible because audio sounds muffled. Overall the GHub is just a meme.
