Factor 10m^5 n^3+5m^4 n^2-25m^2 n ? ?

I am not sure how the answer is coming up as an "m+1+ or "m-1" I am a ... Factor: : 4m^2 -18m + 14. We can simplify this, factor out 2 2(2m^2 - 9m + 7) ... FOIL (5m+3)(m+1) : 15m^2 - 10m - 25. Factor out 5 5(3m^2 - 2m - 5) Factors to 3(3m - 5)(m + 1) FOIL this to confirm it : 50m^3 - 2m. Simplify, factor out 2m 2m(25m^2 - 1)

5m^2 n(2m^3 n^2+m^2 n-5)
Using the exponent rule a^b+c=a^b+a^c
and then factoring out 5nm^2

Where’s the problems ? ?

7p=14 so then you would divide by p=2
