Exemple
:
(-1/2)
2
= (-1/2)
x
(-1/2) = 1/4
A = 5
x
(3/2)
2
-7
x
(5/4) + 2 =
B = 5/6 - (1/2)
2
x
(2/3) =
C = -2
x
(-3/4)
2
+ 5
x
(-3/4) + 2 =
D = a
2
- b
2
(pour a = 1/6 et b = 2/3)
=
E = x
2
+5x -7
(pour x = 7/3)
=
F = -25x
2
-5x +13
(pour x = 2/5)
=
G = 3a
2
- 2a +1
(pour a = 1/2)
=
H = (-5/2)a
2
- a/3 +2
(pour a = 1/4)
=
