Exercice 4 il faut factoriser svppp

Bonjour,

Exercice 4) : Factoriser :

[tex]E = (x + 2)(x + 1) - 5(x + 2)[/tex]

[tex]E = (x + 2)(x + 1 - 5)[/tex]

[tex]\boxed{E = (x + 2)(x - 4)}[/tex]

[tex]F = 25x {}^{2} - 60x + 36[/tex]

[tex]F = 5 {}^{2} x {}^{2} - 2 \times 5x \times 6 + 6 {}^{2} [/tex]

[tex]F = (5x) {}^{2} - 2 \times 5x \times 6 + 6 {}^{2} [/tex]

[tex]\boxed{ F = (5x - 6) {}^{2} }[/tex]

[tex]G = 6x - 15[/tex]

[tex]\boxed{ G = 3(2x - 5)}[/tex]

Bonne journée.
