Answer 1

1) 2(x+y+z)

2) 7x(2x²+x-6+4x³)

4) (x-1)(3x-7)

6) (x-2)(3x-5(x-2)) = (x-2)(3x-5x+10) = (x-2)(-2x+10) = -2(x-2)(x-5)

Answer 2

1)2x+2y+2z=2(x+y+z)

2)14x³+7x²-42x+28x⁴=7x•(2x²+x-6+4x³)

4)3x(x-1)-7(x-1)=(x-1)•(3x-7)

6)3x(x-2)-5(x-2)²=(x-2)•(3x-5(x-2))=(x-2)•(3x-5x+

+10)=(x-2)•(-2x+10)=(x-2)•(-2(x-5))= -2(x-2)•(x-5)
