1 71 3 2 - + - -- + 2*x = --- + - - 1 5 10 2*x 9
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(-551/90)^2 - 4 * (2) * (-3/2) = 400801/8100
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
________ 551 \/ 400801 x1 = --- - ---------- 360 360
________ 551 \/ 400801 x2 = --- + ---------- 360 360
x2 = 551/360 + sqrt(400801)/360
