    Did you mean: (4p3+28p+43p-21)/2p+7 or (4p3+28p+43p-21)/(2p+7)

    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)

    its 4p squared +28 p squared +43p -21 divided by 2p+7 i meant 4p cubed

    \[(4p^2 + 28p^2 + 43p -21)/(2p+7)\] Like this?

    okay so: factor out 4p^2 from the first two expressions: \[(4p^2(p + 7) + 43p -21)/(2p+7)\]?

    Look at this only: 4p^3 + 28p^2 = 4p^2(p + 7)
