Question

8x3+y3 factorise it
​

Answer 1

Answer:

(2x)^3 +y^3

(2x+y)(4x^2+y^2-2xy)

Answer 2

Answer:

( 2 x − y ) ( 4 x 2 + 2 x y + y 2 )

Step-by-step explanation:

In general the difference of cubes can be factored as:

XXX a 3 +b 3 = ( a − b ) ( a 2 + a b + b 2 )  

For the given example:  

a 3 = 8 x 3 =( 2x) 3

and  

b 3 = y 3
