Explications étape par étape
Bonjour,
a = 6x*x -5*x = (6x-5)*x
b= 7y*7y +7y *2 = 7y*(7y+2)
c= 3n*3n - 3n*2= 3n* ( 3n-2)
d= 2* 4t² + 2* 3t +2 * 1= 2 * (4t² +3t +1)
Bonjour,
Factoiser les expressions:
6x²-5x= 6x*x-5*x= (6x-5) *x
49y²+14y= 7y*y+7y*2=7y(7y+2)
9n²-6n= 3n*3n-3n*2= 3n(3n-2)
8t²+6t+2= 2x4t²+2*3t+2*1= 2*(4t²+3t+1)
