Question

(2x-4y)³+(4y-3z)³+(3z-2x)³
with full explanation
and solution ​

Answer 1

Answer:

Let's solve part by part

(2x-4y)³

so we know (a-b)³= a³-b³-3(a-b)

(2x)³-(4y)³-3(2x-4y)

8x³-64y³-6x+12y

(4y-3z)³

again

(4y)³-(3z)³-3(4y-3z)

64y³-27z³-12y+9z

(3z-2x)³

(3z)³-(2x)³-3(3z-2x)

27z³-8x³-9z+6x

NOW LETS ADD ALL TO GET RESULT

(8x³-64y³-6x+12y)(64y³-27z³-12y+9z)(27z³-8x³-9z+6x)

Now let's cancel out the common ones

After cancellation you get answer as
