Question

multiply (4x^2-y)^3

Answer 1

do you know the binomial thrm or pascals triangle?

Answer 2

I know that you do (4x^2-y)(4x^2)(4x^2)

Answer 3

yes

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

then you might want to start with the product of the first two; then include the last one

Answer 4

ok

Answer 5

4x^2 -y
4x^2 -y
-------------
16x^4 -4x^2y
-4x^2y +y^2
-------------------
16x^4 -8x^2y +y^2


then work thru it again with the last term

16x^4 -8x^2y +y^2
4x^2 -y
------------------

Answer 6

so is the final answer 64x^8-15x^4-8x^2y^2-y?
