Help with this math question please?

The problem is 6m³+54m²-6m, another is 5k⁴+8k³-4k², you can answer one or both preferably both, please help I haven't done this type of problem in like 2 years when I was in algebra, this is for summer homework by the way. Thanks for your help and please answer thoroughly so that I can figure out the rest of the problems.

    It's been a while but I think these are right:

    6m^3 + 54m^2 - 6m

    Factored: 6m (m^2 + 9m - 1)

    (^^ there's no further factoring possible. It is a -1 so there is no difference of squares either)

    5k^4 + 8k^3 - 4k^2

    (5k^4 + 10k^3)(- 2k^3 - 4k^2)

    5k^3 (k + 2) - 2k^2 (k+2)

    (5k^3 - 2k^2) (k + 2)

    Factored: k^2 (5k - 2) (k + 2)

    Hope this helped

    Assuming that they are both equal to zero, you need to first simply the equations then set each part equal to zero and solve for the variable.

    6m(m^2+9m-1)=0

    6m=0

    m=0

    Use the quadratic equation to get the rest. A=1, B=9, C=-1

    k^2(5k^2+8k-4)=0

    k^2=0

    k=0

    Use the quadratic equation to get the rest. A=5, B=8, C=-4

    You've presented two quadratic polynomials, but you haven't said what you want to know about them. What is your question? What do you want done with them?
