Question

multiplying polynomials
(a - b)(a 2 + ab + b 2)

Answer 1

Is this supposed to be \((a-b)(a^2+ab+b^2)\)?

Answer 2

yes

Answer 3

If so, then multiply the following...
\(a*a^2\\a*ab\\a*b^2\\-b*a^2\\-b*ab\\-b*b^2\)

Answer 4

a3+a2b+ab2
a2b+ab2+b3
vvvvvvvvvvvvv
a3+a2b+ab2+b3

Answer 5

this is one of the (a-b) to some power. To which, do you know?

Answer 6

\(a*a^2=a^3\\a*ab=a^2b\\a*b^2=ab^2\\-b*a^2=-a^2b\\-b*ab=-ab^2\\-b*b^2=-b^3\\a^3+a^2b+ab^2-a^2b-ab^2-b^3\)

Answer 7

what about this one
(a + 3)(a - 2)

Answer 8

Mine is already completed and solved. And no not (a+3)(a-2)

Answer 9

My example is pretty clear and my result is the same as you would get when multiplying polynomials

Answer 10

Why do you have everything positive @AlondraAcosta ? You are multiplying 3 things by -b
