Bonjour c'est un DM de match c'est a rendre a la rentrer quelqu'un veux bien m'aidez svp?
Factoriser les expressions:
G=15x+25
H=3x²+36x
I=(2x-1)²-4
K=49x²+112x+64
L=25x²-30x+9
Merci a tous,bonne journee

Bonjour,G=15x+25
= 5(3x+5)
H=3x²+36x
= 3x(x+12)
I=(2x-1)²-4
(2x-1-2)(2x-1+2) = a²-b² = (a-b)(a+b) =
(2x-3)(2x+1)
K=49x²+112x+64
= a²+2ab+b² = (a+b)² = (7x+8)²
L=25x²-30x+9
= a²-2ab+b² = (a-b)² = (5x-3)²
G=15x+25 = 5(3x+5)
H=3x²+36x = 3x(x+12)
I=(2x-1)²-4 = (2x-1)² -2² =(2x-1-2)(2x-1+2) =(2x-3)(2x+1)
K=49x²+112x+64 =(7x+8)²
L=25x²-30x+9 =(5x-3)²
