Question

Factor by finding the GCF
a) 4w^2+18w
b) n^5 +7n^3 -8n^2
c) 16x^4-8x^3 +24x^7
d) 27x^3y^4 -45xy^3 +36x^2y^2

Answer 1

for each problem follow the same process

find the prime factors of each term then take out what is in both groups
example a) 2*2*w*w and 2*3*3*w common is 2*w

c) 16, 8 and 24 lowest is 8
x^4, x^3, x^7 lowest is x^3
greatest common factor 8 x^3

Answer 2

@triciaal can you give me an example of this using part a? btw what are prime factors?

Answer 3

a prime number is a number that can only be divided by one and itself
a prime factor is a factor that is a prime number
