Salut !
fractionner ????
ou bien factoriser.....?
(6x+8)(10x+5)+6x+8
= (6x+8)(10x+5)+(6x+8)(1)
= (6x+8)(10x+5+1)
= (6x+8)(10x+6)
= (6x+8)2(5x+3)
= 2(3x+4)2(5x+3)
= 4(3x+4)(5x+3)
Bonsoir,
factoriser:
(6x + 8) (10x + 5) + 6x + 8= (6x+8)(10x+5+1)= (6x+8)(10x+6)= 2*2(3x+4)(5x+3)
= 4((3x+4)(5x+3)
explication:
(6x+8)= 2(3x+4) et (10x+6)= 2(5x+3)
