bonjour aidez moi svp

Simplifier les écritures :

• 6 × x = ……………………………….
• ( - 3 ) × x = ……………………….
• 5 × x × ( - 4x ) = ……………………
• x × ( - x ) = …………………….
• x × ( - 7 ) × ( - x ) = ……………………
• ( - 5 ) × ( 2x – 7 ) = ……………………………………….
• ( + 6 ) × ( x + 3 ) = …………………………………….
• 3x × ( - 5x ) = …………………………….
• 3x + ( - 5x ) = ………………………….
• - 3x – 5x = ……………………………….

Réponse :

6 × x= 6x

( - 3 ) × x = -3x

5 × x × ( - 4x ) = -20x²

x × ( - x ) = -x²

x × ( - 7 ) × ( - x ) = 7x²

( - 5 ) × ( 2x – 7 ) =  -10x+35

( + 6 ) × ( x + 3 ) = 6x+18

3x × ( - 5x ) = -15x²

3x + ( - 5x ) = -2x

- 3x – 5x = -8x
