Question 106263: Factor completely:
x^10y^3 – 4x^9y^2 – 21x^8y
If you believe that a polynomial is not factorable, label it as prime. Show all stages of factoring separately (i.e., show the result of factoring out a GCF before taking the resulting polynomial and factoring it again).
I am stuck on this one. Thanks in advance!

Factor completely:
x^10y^3 – 4x^9y^2 – 21x^8y
= x^8y[x^2y^2 - 4xy - 21]
= x^8y [xy-7][xy+3]
