bonjour
(−9x−6)(4x+3)−7(−9x−6)
( - 9 x - 6 ) ( 4 x + 3 - 7 )
= ( - 9 x - 6 ) ( 4 x - 4 )
= 4 ( - 9 x - 6 ) ( x - 1 )
(−9x−2)(5x−3)−(−9x−2)(5x+3)
( - 9 x - 2 ) ( 5 x - 3 - 5 x - 3 )
= - 6 ( - 9 x - 2 )
(5x+4)²+(5x+4)(8x−6)
= ( 5 x + 4 ) ( 5 x + 4 + 8 x - 6 )
= ( 5 x + 4 ) ( 13 x - 2 )
x²−2xy+y²
= ( x - y )²
