Math Homework Question?

Question

This is the problem and the work I have done ... is it right? If not where did I go wrong?
Thanks,
Jennifer

(x + 1) (x2 – x + 1)
(x * x) + (x * 1) + (1 * x2 ) + (1 * 1) – x
X3 + x + x2 + 1 – x
X3 + x2 + 1
(The number after the x is an exponent)

Thanks in advance for any help!

Answer 1

no its wrong. You have to use FOIL. no idea what it stands for but it means multiply the first number(in this case X, by each # in the second perinthyses, then the 1)

you should come up with:

x3 - x2 + x + x2 - x + 1

then the -x2 and +x2 cancel out and so do the -x and the +x

so now you have x3+1

Answer 2

the answer's x^3 + 1
(x + 1)(x^2 - x + 1)
[x(x^2 - x + 1)] + [1(x^2 - x +1)] multiply x through x^2 - x + 1, then multiply 1 through x^2 - x + 1
x^3 - x^2 + x + x^2 - x +1 combine like terms
x^3 + 1

Answer 3

x^3 - x^2 + 1x + x^2 - 1x + 1
that is what i got when i used FOIL (distributive property)
simply to:

x^3 + 1

Answer 4

Could you please write this problem a little more clearly. Can't understand what it is try writing (x * x) like this x^2. It'll be easier to understand then I could solve it.

Answer 5

that's right. just remeber to always combine like terms and use the order of operations.

Answer 6

wow yr pretty good!
very very very very nice work

congrats!

Answer 7

ah that was right
