𝑥^3 − 512

Answer:

𝑥^3 − 512

According to the equation,

𝑎^3 − 𝑏^3 = (𝑎 − 𝑏)(𝑎^2 + 𝑎𝑏 + 𝑏^2)

So we get,

𝑥^3 − 512

= 𝑥^3 − 8^3

Using the equation,

= (𝑥 − 8)(𝑥^2 + 8𝑥 + 8^2)

= (𝑥 − 8)(𝑥^2 + 8𝑥 + 64)

"hello guys welcome back to leader
homework i'm reverend kumar working as
the tutor that we do
so today we are going to solve very easy
and very interesting question
so let's see how we can do it and how we
can solve it okay so it is exactly in
the format
of x cube minus eight whole cube five
one two is in the
for like or this cube of eight cube
right so that is again in the format of
a cube minus b cube so a cube minus b
cube means we have this formula that is
a minus b of
a square plus a b plus b square so just
substitute all the values here
so after substituting this a is equals
to x right so a is equals to x
and b is equals to 8 then x minus
8 of x squared
plus a square means x square plus 8x
plus 64. so that is our final answer
here
so this is the thing after substitution
we got so
i hope you understood what i've done
here if you have any doubts please
