Question

-2a+3a=

-7b-4b=

-7×+2×+4×=
-8y-y+3y=
-6×y+7z-4xy+z=
-(5×)(3×)=
-2y (3y+4a)=
-4a (3×-5a)=
-(2a-3×+6y)4=
-3 (z+5a-8×+4)=

Answer 1

-2a+3a= a(-2+3)=a

-7b-4b=b(-7-4)=-11b
-7×+2×+4×=x(-7+2+4)=-x-8y-y+3y=y(-8-1+3)=-6y-6×y+7z-4xy+z=xy(-6-4)z(7+1)=-10xy+8z-(5×)(3×)=--2y (3y+4a)=-4a (3×-5a)=-(2a-3×+6y)4=-3 (z+5a-8×+4)=
