factor out the GCF

Question

-8s^4 + 20t^3 - 28
6n^6 + 18n^4 - 24n
-5m^4 - 5m^3 + 5m^2

Answer 1

-8s^4 + 20t^3 - 28
GCF: 4
Factor out the GCF: 4(-2s^4 + 5t^3 - 7)

6n^6 + 18n^4 - 24n
GCF: 6n
Factor out the GCF: 6n(n^5 + 3n^3 - 4)

-5m^4 - 5m^3 + 5m^2
GCF: -5m^2
Factor out the GCF: -5m^2(m^2 + m - 1)
