K = (x + 3)(x + 8)
L = (2x + 4)(x + 1)
M = (x² + 1)(x + 2)
N = (x² - 3)(-2x + 4)​

bonsoir

Explications étape par étape :

K =(x+3)(x+8)

K = x²+8x + 3x + 24

K = x² + 11x + 24

L = (2x + 4) ( x+ 1 )

L = 2x² + 2x + 4x + 4

L = 2x² + 6x + 4

M = (x²+ 1 )(x + 2 )

M = x³ + 2x² + x + 2

N = (x²- 3 )(-2x + 4 )

N = -2x³ + 4x²+ 6x -12
