I've worked these problems but I was just wondering if someone could check over them to see if they're correct...if not please help!

my answer: 7u^2-49u

my answer: 25t^2-40+16

Thank you :)

  • math -

    hmm, well use either FOIL or the distributive property. I will use distributive property:
    my answer: 7u^2-49u
    u(u+7) -2(u+7)
    u^2 + 7u - 2u - 14
    u^2 + 5 u - 14
