Question

factorise P - q q + Q - R cube plus or minus b cube

Answer 1

hope so this will work.....mark brainiest plzz

Answer 2

$( p - q )^3 + ( q - r )^3 + ( r - p )^3=3(p-q)(q-r)(r-p)$

Step-by-step explanation:

To find : Factories $(p-q)^3+(q-r)^3+(r-p)^3$

Solution :

Let a = ( p - q)

b = ( q - r )

c = ( r - p )

Now we add all of them,

a + b + c = p - q + q - r + r - p

a + b + c = 0

Using Identity,

If a + b + c = 0 then a³ + b³ + c³ = 3abc

i.e. $( p - q )^3 + ( q - r )^3 + ( r - p )^3=3(p-q)(q-r)(r-p)$
