    Could you please show me how to simplify these expressions?


    For a I got p(2p^3+11p^2+10p)-12
    b) t(2t^2+9t+22)+38
    but I'm not sure if this is correct

    EDIT: Soz- it didn't attach first time

    Dunno they look pretty simplified as it is (though there's a cheeky difference of 2 squares in the first one). Unless you need to expand them, in which case just multiply 2 brackets at a time.

    so for a have (p+1)(p-1)(P+4)(2p+3)?

    I multiplied everything out and tried to simplify/factorise what I had left but it didn't really work... I ended up with 2p^4+11p^3+10p^2-11p-12
    so then I just took the p out and factorised it and put a -12 at the end:

    p(2p^3+11p^2+10p)-12

    Well I dunno what you are being asked to do with it??? If it's to expand it, then yeah you got it right. If it's to factorise it further, then it's just the difference of 1 squares and you're done.
