Answer 1

question 1
(x+y)(x^2-xy+y^2)
x^3-x^2y+y^2x+yx^2-xy^2+y^3
simplify
x^3-x^2y+y^2+y^3

question 2
(x^2-4)(x^2-2x+1)
x^4-2x^3+x^2-4x^2+8x-4
then simplify
x^4-2x^3-3x^2+8x-4

question 3
(5-2a)(2-3a-a^2)
10-15a-5a^2-4a+6a^2+2a^3
then simplify
2a^3+a^2-19a+10

question 4
(1-2x)(3+2x-x^2)
3+2x-x^2 -6x-4x^2+2x^3
simplify
2x^3-5x^2-4x+3

Answer 2

1) (x+y)*(x-y)^2= (x^2-y^2)(x-y)= x^3-x y^2-y x^2+y^3
2) x^4-4x^2-2x^3+8x+x^2-4= x^4-2x^3-3x^2+8x-4
3) 10-4a-15a+6a^2-5a^2+2a^3=2a^3+a^2-19a+10
4) 3-6x+2x-4x^2-x^2+2x^3= 2x^3 -5x^2-4x+3

Answer 3

This is not a question. This is simply a list of math problems and a statement commanding people to solve them. This does not help you and it certainly does not help me.

If you really want to get help solving these problems, then please ask specifically what you are having trouble with. Once you can solve one of these problems yourself, you should be fine with the others.

So, please try to work the problems yourself. And then, if you get stuck, ask how to solve the problem that you are stuck on. Don't just tell me to solve problems for you.

Answer 4

You are still a kid or are you kidding?Can solve these in a jiffy but not the clever way you think so.Wait for some simpleton.

Answer 5

There's no equations to solve.

Answer 6

1........-a^3+27 2........2x^3-5x^2-11x-4 3........3a^3+a^2-4a+12 4........2p^2-p-pq+2q-6q^2 i hope these are correct !!

Answer 7

I agree do it yourself..

Answer 8

or you can just do your own homework. duh
