Question

Factories 8x³ - (2x –y) ³

Answer 1

Answer:

Refer to the attachment above

Answer 2

Answer:

Here is your answer.

Step-by-step explanation:

...difference of cubes:

(a^3 - b^3) = (a - b_(a^2 + ab + b^2)

where a = (2x)^3

and b = (2x - y)^3

you have the pattern...give it a go !

id est

[8x^3 - (2x - y)^3 = (2x - (2x - y))(4x^2 + 2x(2x - y) + (2x - y)^2 =

y(8x^2 - 2xy + (4x^2 - 4xy + y^2)) = y(12x^2 - 6xy + y^2)]

check by expanding...

Hope it helps you !!
