Question

6v-81v^3

Answer 1

thats wrong sorry

Answer 2

its 64v-81v^3

Answer 3

64v-81v^3


v(64-81v^2)


v(8^2-(9v)^2)


v(8-9v)(8+9v) .. use the difference of squares factoring formula here



So 64v-81v^3 factors to v(8-9v)(8+9v)

Answer 4

v(64-81v^2). Now the trick here is to make the inside of the parentheses negative to get the v^2 to be positive so -v(81v^2-64). Now, it's just simple difference of two squares resulting in -v(9v+8)(9v-8)
