-1000X^2+3000X-3000=657^-1
We move all terms to the left:
-1000X^2+3000X-3000-(657^-1)=0
We add all the numbers together, and all the variables
-1000X^2+3000X-3000.00152207=0
a = -1000; b = 3000; c = -3000.00152207;
Δ = b2-4ac
Δ = 30002-4·(-1000)·(-3000.00152207)
Δ = -3000006.08828
Delta is less than zero, so there is no solution for the equation
