Bonsoir

DEVELOPPER LES EXPRESSIONS :

B ( x ) = (x-3)²-1

B(x) = x² - 6x + 9 - 1

B(x) = x² - 6x + 8

C ( x ) = (x-1)(x-5)+2

C(x) = x² - 5x - x + 5 + 2

C(x) = x² - 6x + 7

D ( x ) = (x-4)(x-2)

D(x) = x² - 2x - 4x + 8

D(x) = x² - 6x + 8

Bonjour

B ( x ) = (x-3)²-1

X^2 -6x + 9 -1

X^2 -6x + 8

C ( x ) = (x-1)(x-5)+2

X^2 -5x-x+ 5 + 2

X^2 -6x+7

D ( x ) = (x-4)(x-2)

X^2 -2x -4x + 8

X^2 -6x + 8
