Question

Factor the ff :

125-y3 =
x3y3-93 =
b3-1000 =

Thanks :)

Answer 1

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

Answer 2

\[
125 - y^3 = 5^3 -y^3=(5-y)(25+ 5 y + y^2)
\]
Mimic this one to finish the other two.

Answer 3

Can you do the other two?

Answer 4

What about the last two numbers please :(

Answer 5

Are you sure that the second one is
\[x^3 y^3 - 93
\]

Answer 6

\[
b^3 - 1000=b^3 - 10^3=(b-10)(b^2 +10b + 100)
\]
