Fill in the missing factors and factor the following expressions in prime polynomials?

I. Fill in

1) x(a-2b) + 3(a-2b) = (___) (a-2b)

2) 7x(a-b) - 9y(a-b) = (___) (a-b)

3) x(a-3b) + y(3b-a) = x(a-3b) - y(___) = (x - y) (___)

4) v(4m-n) + w(n-4m) = v(4m-n) - w(___) = (v-w) (___)

5) 3a^2 - ^ab + 2a - 4b = 3a(a-2b) + 2(a-2b) = (___) (___)

II. factor into prime polynomials

1) 3x^2 - 9xy = 2x - 6y

2) 10x^2y - 15xy = 8x^2 - 12x

3) 6m^2x - 9m^2y - 14n^2x = 21n^2y

4) 16x^2y^2 - 8xyz = z^2

5)x^2 = 18x + 81

so there.

just seeing if there's anyone out there who can answer these numbers. i answered them in less then five minutes. what about you? first answer gets best answer!!

p.s.

dont forget solutions or i'll think you cheated.

Update:

Alvaro, i have sooo answered this already. too bad you can't.

Update 2:

the ^ sign indicates an exponent.

like ^2 is squared, ^3 is cubed, and so on.

    1 x+3

    2 7x-9

    3 x(a-3b)-y(a-3b)=(x-y)(a-3b)

    4 v(4m-n)-w(4m-n)=(v-w)(4m-n)

    5 (3a+2)(a-2b)

    to get ans for ques 2. specify what sign is this '^' ?
