Question

Factor the following using the GCF: 10xy3 - 25x2y2 + 15xy

Answer 1

im just confused with gcf

Answer 2

GCF = 5xy

Answer 3

5xy my man.

Answer 4

GCF is greatest common factor
for numbers you can find it by first factoring them into primes:
10 = 2*5
25 = 5*5
15 = 3*5

5 is common to all 3 so GCF is 5

as for the letters it is the one with lowest power:
x , x^2, x - GCF is x

y^3, y^2 , y - GCF is y

Answer 5

Think of it this way: the biggest number that will divide into all the numbers. If it's powers think the biggest power they have in common.
