9*x 5*x 144 + -0.31640625 - --- - 1.5625*x*x = x*x + --- + 1.5625 8 2
a*x^2 + b*x + c = 0
D = b^2 - 4 * a * c =
(-29/8)^2 - 4 * (-2.5625) * (142.121093750000) = 1469.8818359375
x1 = (-b + sqrt(D)) / (2*a)
x2 = (-b - sqrt(D)) / (2*a)
suma
-8.18810497859227 + 6.77347083225081
=
-1.41463414634146
producto
-8.18810497859227*6.77347083225081
=
