Question

1) Scoateti factorul comun:
b) 2x-4y+10z+12t;
d)7a²b-14ab²+21a²b²;
2) Scoateti factorul comun:
b)5(2x-3)-x(2x-3);
d)3x(x+5)-2(x+5);
Va roog.

Answer 1

b) 2x-4y+10z+12t=
=2(x-2y+5z+6t)

d)7a²b-14ab²+21a²b²=
=7ab(a-2b-3ab)

2) Scoateti factorul comun:
b)5(2x-3)-x(2x-3)=
=(2x-3)(5-x)

d)3x(x+5)-2(x+5)=
=(x+5)(3x-2)

Answer 2

2x-4y+10z+12t= 2( x-2y +5z +6t) ; d)7a²b-14ab²+21a²b²= 7ab( a- 2b +3ab); b)5(2x-3)-x(2x-3) =(2x-3)(5-x) ; d)3x(x+5)-2(x+5) = ( x+5)(3x-2) ;
