Desccompuneti in factori :
a)5x+5y+5z
b)3x-9y+6z
c)3x(x+1)-5(x+1)
d)12x(2x-1)-6(2x-1)

Răspuns :

a)5(x+y+z)
b)3(x-3y+2z)
c)(x+1)(3x-5)
d)(2x-1)(12x-6)=6(2x-1)(2x-1)
                        =6(2x-1)²

a)5x+5y+5z=5(x+y+z)
b)3x-9y+6z=3(x-3y+2z)
c)3x(x+1)-5(x+1)=(x+1)(3x-5)
d)12x(2x-1)-6(2x-1)=(2x-1)(12x-6)=6(2x-1)(2x-1)=6(2x-1)²
