Question

GCF
10a^2b + 16ab^2
11a^3b - 2a^2b^4
36a^4 + 27a^3b
3a^2b^2 + 18ab^3 - 33b^4
4a^4b^2 - 9a^3b^3 + a^2b^4
75a^5b^3 + 30a^3b^5 - 60ab^7

Answer 1

1) 10a^2b + 16ab^2
GCF = 2ab
Factor: 2ab(5a + 8b)

2) 11a^3b - 2a^2b^4
GCF = a^2b
Factor: a^2b(11a - 2b^3)

3) 36a^4 + 27a^3b
GCF = 9a^3
Factor: 9a^3(4a + 3b)

4) 3a^2b^2 + 18ab^3 - 33b^4
GCF = 3b^2
Factor: 3b^2(a^2 + 6ab - 11b^2)

5) 4a^4b^2 - 9a^3b^3 + a^2b^4
GCF = a^2b^2
Factor: a^2b^2(4a^2 - 9ab + b^2)

6) 75a^5b^3 + 30a^3b^5 - 60ab^7
GCF = 15ab^3
Factor: 15ab^3(5a^4 + 2a^2b^2 - 4b^4)
