welcome to open study please read the code of conduct http://openstudy.com/code-of-conduct

OpenStudy (anonymous):

\[280=\frac{ -2 }{ 1575}(x-525)^{2}+350\] Is this right?

OpenStudy (anonymous):

\[x^2-1050 x+220500=0 \]That is what I got after simplification and it can not be factored.

A plot is attached.
