2 33*z 89 z - ---- - --- = 0 100 100
a*z^2 + b*z + c = 0
D = b^2 - 4 * a * c =
(-33/100)^2 - 4 * (1) * (-89/100) = 36689/10000
z1 = (-b + sqrt(D)) / (2*a)
z2 = (-b - sqrt(D)) / (2*a)
_______ 33 \/ 36689 z1 = --- - --------- 200 200
_______ 33 \/ 36689 z2 = --- + --------- 200 200
z2 = 33/200 + sqrt(36689)/200
suma
_______ _______ 33 \/ 36689 33 \/ 36689 --- - --------- + --- + --------- 200 200 200 200
=
