1. 3a+63b= 2.8b²+6b=
3. 2ab-2ay=
4. 8a²b-4ab2=
5. 4x(x-1)-x+1
6. x(2a-B)-y(b-2a)=
7. a(x-y)-(y-x)=
8. (3x-1)(x-2)-(x+4)(x-2)=
9. (a+B)(x-3y)-2a(x-3y)=
i have to simplify

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

If f(x) =3x-2 and g(x) =2x+1 fins (f+ g) (x)
