Bonsoir,
1)
E = (x + 3)² - (x + 1) (x + 2)
E = x² + 6x + 9 - (x² + 2x + x + 2)
E = x² + 6x + 9 - x² - 2x - x - 2
E = 6x - 2x - x + 9 - 2
E = 3x + 7
2) 10 003 - 3 = 10 000
10 001 - 1 = 10 000
10 002 - 2 = 10 000
Soit x = 10 000
3 * 10 000 + 7
= 30 007
Ainsi, en appliquant la forme developpee et reduite,
10 003² - 10 001 x 10 002 = 30 007
Bonne soiree
