2 3*x 57*x 189 ---- - ---- - --- = 0 5 25 25
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(-57/25)^2 - 4 * (3/5) * (-189/25) = 14589/625
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
______ 19 \/ 1621 x1 = -- - -------- 10 10
______ 19 \/ 1621 x2 = -- + -------- 10 10
x2 = 19/10 + sqrt(1621)/10
