Factor each expression completely. Can you please show me the steps for these. I'm so confused and don't know how to do them. Thank you so much!!

kx^3+2kx^2-63kx

and

3xz^2+42xyz+99xy^2

  • Math -

    take out kx
    kx (x^2 +2x -63)

    now take 3x out of the next one
    3x (z^2 +14 yz +33y^2)
    3x (z+11y)(z+3y)
