49*10000000000000 2 863*100000000000 10000000000000*(-14) -----------------*x + ----------------*x + -------------------- = 0 25 100 5
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(863000000000)^2 - 4 * (19600000000000) * (-28000000000000) = 2195944769000000000000000000
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
____________ 863 \/ 2195944769 x1 = - ----- + -------------- 39200 39200
____________ 863 \/ 2195944769 x2 = - ----- - -------------- 39200 39200
x2 = -sqrt(2195944769)/39200 - 863/39200
