Answer 6

-2.5x^2+2825x-115812.5=500000
Rationalize the decimal fraction coefficients.\[-\frac{5}{2}\left(x^2\right)+2825x-\frac{231625}{2}=500000 \]Multiply both equation sides by -2/5, move the RHS to the LHS and simplify:\[x^2-1130 x+246325=0 \]The equation can be factored.\[(x-835) (x-295)=0 \]@saifoo.khan listed the solutions in the postings above.
