Question

expand (x^6-y^6)

Answer 1

ok

Answer 2

\[(x ^{3})^{2}-(y ^{3})^{2}\]

Answer 3

Start with that, then expand according to the formulae.

Answer 4

what formulae

Answer 5

a^2 - b^2

Answer 6

difference of squares

Answer 7

\[(x ^{3})^{2}-(y ^{3})^2 = (x ^{3}+y ^{3})*(x ^{3}-y ^{3})\]

Answer 8

Now apply the formula for x^3 + y^3 and x^3 - y^3

Answer 9

i do not the formulae you speak of

Answer 10

what is it called?

Answer 11

(a^3-b^3)=(a –b)(a²+ ab+ b²)

Answer 12

is that the formulae

Answer 13

\[(x ^{3})^{2}-(y ^{3})^{2}=(x ^{3}+y ^{3})*(x ^{3}-y ^{3})=[(x-y)*(x ^{2}+xy+y ^{2})]*[(x+y)*(x ^{2}-xy+y ^{2})]\]

Answer 14

i can not see it all

Answer 15

Expand (x^3 +y^3) and (x^3-y^3)
(x^3+y^3) = (x+y)*(x^2+y^2-xy)
(X^3-y^3) = (x-y)*(x^2+xy+y^2)

Answer 16

great job thanks
