Did you mean: (4p3+28p+43p-21)/2p+7 or (4p3+28p+43p-21)/(2p+7)
anonymous
  • anonymous
the second one
bahrom7893
  • bahrom7893
okay so: rewrite the top as: [4p(p^2+7)+43p-21)]/(2p+7)

[4p(p^2+7)+43p-21)]/(2p+7) = [p{4(p^2+7)+43}-21)]/(2p+7)

this is kinda hard to simplify r u sure the problem is correct?
anonymous
  • anonymous
its 4p squared +28 p squared +43p -21 divided by 2p+7 i meant 4p cubed
bahrom7893
  • bahrom7893
okay

does that seem right
bahrom7893
  • bahrom7893
\[(4p^2 + 28p^2 + 43p -21)/(2p+7)\] Like this?

exactly but its 4p cubed
bahrom7893
  • bahrom7893
\[(4p^3 + 28p^2 + 43p -21)/(2p+7)\]?
anonymous
  • anonymous
yep
bahrom7893
  • bahrom7893
okay so: factor out 4p^2 from the first two expressions: \[(4p^2(p + 7) + 43p -21)/(2p+7)\]?

i'm confussed
bahrom7893
  • bahrom7893
Look at this only: 4p^3 + 28p^2 = 4p^2(p + 7)
bahrom7893
  • bahrom7893
do u get it?
anonymous

what does ^ mean
bahrom7893
  • bahrom7893
to the power (four p cubed)

okay so wat answer did you come up with i got 6r8p
bahrom7893
  • bahrom7893
where the heck did r come from?
bahrom7893
  • bahrom7893
what is r? radical?

I got 16p^2 + 56p - 24?
bahrom7893
  • bahrom7893
woops I meant (1/8)*(16p^2 + 56p - 24)
