Question

factor 81v^6-3d^6

Answer 1

3(27v^6 - d^6)

= 3((3v^2)^3 - (d^2)^3)

= 3(3v^2 - d^2)(9v^4 + 3v^2*d^2 + d^4)

= 3(v*sqrt(3) - d)(v*sqrt(3) + d)(9v^4 + 3v^2*d^2 + d^4)

Answer 2

3(v*sqrt(3) - d)(v*sqrt(3) + d)(9v^4 + 3v^2*d^2 + d^4)
is this
3(v^3-d)(v^3+d)(9v^4+3v^2 not sure the rest please help is it times or ?

Answer 3

yes than (... )(---) so there is multiplication - product - times
