Bonjour,

C = 2 (5x - 1)² + 10x - 2

C = 2 (5x - 1)² + 2 (5x - 1)

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

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

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

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

C = 10x (5x - 1)

Bonjour,

C=2(5x-1)2+10x-2

= 2(5x-1)²  + 2( 5x-1)

= 2( 5x-1) (5x-1)  + 2(5x-1)

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

= (10x -2) ( 5x)
