    can someone check this for me...

    The problem is:
    10x^5(-x^2+2x-3)

    = -10x^7+20x^6-30x^5

    Then factor it again:
    10x^5(-x^2+2x-3)

    Hi nfgcharlottegr108,

    Is this what you have?

    10x^5(-x^2+2x-3)

    If it is, then

    -10x^7+20x^6-30x^5

    ....and you are correct!!
