    correct

  • factroing monomials -

    what about 8a+10b-16= 2(4a+5b-8)

    3c^4-6c^2-15c= 3(c^4-2c^2-3)

  • factroing monomials -

    first one is correct, the second should be

    3c^4-6c^2-15c= 3(c^4-2c^2-5)

    You could easily check if you are correct by simply expanding your answer.
