(3x + 2)(2x - 1)+(4x - 2)(3 - 5x)
= (3x + 2)(2x - 1) + 2(2x-1)(3- 5x)
= (2x - 1)[(3x+ 2) + 2(3- 5x)]
=(2x - 1)(3x + 2 + 6 - 10x)
=(2x - 1)(3x - 10x + 2 + 6)
=(2x - 1)(-7x + 8)
bonjour
(3x + 2)(2x - 1)+(4x - 2)(3 - 5x)
( 3 x + 2 ) ( 2 x - 1 ) + 2 ( 2 x - 1 ) ( 3 - 5 x )
= ( 2 x - 1 ) ( 3 x + 2 + 6 - 10 x )
= ( 2 x - 1 ) ( - 7 x + 8 )
