a^4+2a^2b^2+b^4-2ab
hey i just wanna know if this is right also,
is there a shorter way to solve this question
check Attachment

Note: where the dots are they are x (times) was using a online calculator

ty in advance

 

[lolokay]

woah what's going on there

it's using difference of two squares
(a²+b²)² - 2ab
= (a²+b² + sqrt{2ab})(a²+b² - sqrt{2ab})
