Mathématique.
Exercice n°1 = Développer, réduire et ordonner à l'aide des identités remarquables quand c'est possible.
1. A = ( 2 x + 3)²
2. B = ( 5x - 4)²
3. C = ( 9x - 4) (9 x + 4)
4. D = (2 x -3) (5x +4) + (9x -4) (3x + 2)
5. E = ( 2x - 3) (5x + 4) - (9x -4) - (9x -4) (3x +2)
Quelqu'un pourrais me donner toutes les réponses s'il vous plaît, je vous remercie...!!!

1. A = ( 2 x + 3)²
A = 4x² + 12x + 9
2. B = ( 5x - 4)²
B = 25x² - 40x + 16
3. C = ( 9x - 4) (9 x + 4)
C = 81x² - 16
4. D = (2 x -3) (5x +4) + (9x -4) (3x + 2)
D = 10x² + 8x - 15x - 12 + 27x² + 18x - 12x - 8
D = 37x² - x - 20
5. E = ( 2x - 3) (5x + 4) - (9x -4) - (9x -4) (3x +2)
E = 10x² + 8x - 15x - 12 - 9x + 4 - 27x² - 18x + 12x + 8
E = - 17x² - 13x - 4

Les 3 premiers restes tel qu'il sont.
I
=
( 2x - 3)² - 25
=
(2x x 2x) + (2x x (-3)) + (-3 x 2x) + (-3 x (-3))
=
4x² + (-6x) + (-6x) + 9 + (-2) = -2
et
-6 x -6 = 6 x 6
=
4x² -6x -6x +9 = 4x² +12x +9
Essaye les autres en te basant sur le I et si t'y arrive vraiment pas demande.
