[tex]a)7x(2 - 3x) \\ = 7x \times 2 - 7x \times 3x \\ = 14x - 21 {x}^{2} [/tex]

[tex]b) - 8( - 2y - 6) \\ = - 8 \times (- 2y )- 8 \times ( - 6) \\ = 16y + 48[/tex]

2)

[tex]c)2 {x}^{2} - 3x \\ = x(2x - 3)[/tex]

[tex]d)14y + 21 \\ = 7(2y + 3)[/tex]

Et voilà j'espère t'avoir aidé

A= 7x(2−3x)

=7x×2+7x×−3x

=14x+7x×−3x

=14x+(7×−3)xx

=14x−21xx

[tex]a = 14x - x {}^{2} [/tex]

B= −8×−2y−8×−6

=16y−8×−6

=16y−(−48)

B= 16y+48

2)

C=

[tex]2x {}^{2} - 3x[/tex]

[tex]x( \frac{2x {}^{2} }{3} + \frac{ - 3x}{x} )

[/tex]

[tex]c = x(2x - 3)[/tex]

D = 14y + 21

[tex]= 7( \frac{14y}{7} + \frac{21}{7} )[/tex]

D =7(2y+3)
