Exercice 4 il faut factoriser svppp

Bonjour,

Exercice 4) : Factoriser :

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

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

$\boxed{E = (x + 2)(x - 4)}$

$F = 25x {}^{2} - 60x + 36$

$F = 5 {}^{2} x {}^{2} - 2 \times 5x \times 6 + 6 {}^{2}$

$F = (5x) {}^{2} - 2 \times 5x \times 6 + 6 {}^{2}$

$\boxed{ F = (5x - 6) {}^{2} }$

$G = 6x - 15$

$\boxed{ G = 3(2x - 5)}$

Bonne journée.
