Give a quadratic form $q = sum_{i=1}^{p}alpha_i f_i^2$ where $f_i in E^{*}$ and $alpha_iin mathbb{K},$ show that $text{rank}(q)leq text{rank}(f_1,f_2,cdots,f_p).$
I think this makes sense but for some reason, I am not sure how to prove this statement. I tried to proceed with contradiction, but that does not seem to lead me anywhere.
