Thank you, professor!

令y=10-x 則x(10-x)=100 x^2-10x+100=0 (x-5)^2=-75 x-5=+-5√3i 則x=5+5√3i. y=5-5√3i

Если так решать, то видео слишком коротким получится. :)))

Does that count as a final solution? Maybe I don’t understand comprehensively enough, but I tend to think of eye some mathematical space holder and here you just have it in the final form there’s no real number that satisfies this right? Doesn’t that mean there isn’t actually an answer that your final answer can’t do away with the eye?

I’d rather complete the square early on than run through the QF

(25*3-1)=74 not 75

There is a multiplication sign between 3 and -1

@@Hsauzier ok ty it was my bad i didn´t catch that

What a waste of time that was , you didn’t find the true value of x or y. What is the square root if i ? Is it H 🎉
