Bonjour

( x + 2 ) ( 5 - x )

( x - 1 ) ( x + 8 - 2 ) = ( x - 1 ) ( x + 6 )

( 3x + 4 ) ( 2x + 6 - 1) = ( 3x + 4 ) ( 2x + 5 )

(x-2)(-x+2+5x+8) = ( x-2) ( 4x - 10) = 2 (2 x - 5 ) ( x-2)

(x²-3)(2x+1+17) = ( x² - 3 ) ( 2x + 18 ) = 2 ( x +9) (x² -3)

( √ 3 x - 1) ( -3 * ( √3 x - 1 ) ) = ( √ 3 x - 1) ( -3√3 x+ 3 ) = 3 ( -√3x + 1 ) ( √ 3x - 1 )

Bonne fin de journée
