I used to be indecisive, but now I’m not so sure...

I used to be narcissistic, but now I'm perfect...

comment Writing $1$ as a Linear Combination of Polynomials
@dafinguzman I think it is $4x + 2t + 1$. wolframalpha.com/input/?i=%28t%5E3+%2B+5*tx%5E2+%2B+1%29+-+t*%28t%5E‌​2+%2B+x%5E2+-+2%29+-4*x*%28tx+-+1%29

comment Linear combination of quadratics that vanish on a line
The question comes from the section on algebraic geometry. I just skimmed the 1st edition and couldn't find the problem there, either.

@DonAntonio Sorry, the book is 'Algebra' by Michael Artin (2nd ed.)

@DonAntonio This is a question from Artin chapter 11, exercise 9.11.

comment Linear combination of quadratics that vanish on a line
@DonAntonio The phrasing in the book says "quadratic polynomials", but I think your right. What is the definition of a two-variable quadratic? Is it $ax^2y^2 + bxy^2 + cx^2y + \dotsb?$.
