Bonjour Pourriez me corriger les fautes qu'il y a dans mes calcule de DM (qui sera noté) s'il vous plaît :-) :
A = ( 7x - 1 ) ( 2x + 5 )
A = 14x² + 35x - 5
A = 14x² +33x -5
B = ( -2x + 2 ) ( x - 6 )
B = -2x² + 12x + 2x - 12
B = -2x² + 14x - 12
C = ( 5x - 1 ) ( 2x - 8 ) + ( x + 1 )²
C = ( 5x - 1 ) ( 2x - 8 ) + ( x + 1 ) ( x + 1 )
C = 10x² - 40x - 2x + 8 + x² + 1x + 1x + 1
C = 11x² - 40x + 9
D = ( 2x - 5 ) + ( 8x - 2 )
D = 10x - 7
E = ( -9x - 5 ) - ( 2x + 5 )
E = -9x - 5 + 2x - 5
E = -11x - 10
F = 2 - 5x + ( 1 - 3x + 2x² ) + 4x² - ( x - 7 )
F = 2 - 5x + 1 - 3x + 2x² + 4x² + x + 7
F = 6x² - 7x + 10
J = ( 3x + 3 ) ( x + 4 ) - ( 3x - 1 ) ( 6x - 2 )
J = ( 3x + 3 ) ( x + 4 ) + ( 3x + 1 ) ( 6x + 2 )
J = 3x² + 12x + 3x + 12 + 18x² + 6x + 6x + 2
J = 21x² 27x + 14
H = 4 ( 2x - 8 ) - ( 4 + x )
H = ( 8x - 32 ) - ( 4 + x )
H = ( 8x - 32 ) + ( 4 - x )
H = 32x - 8x² - 128 - 32x
H = 8x² + 0x - 128
MERCI d'avance :-)
