Question

Someone please show me how to find the greatest common factor of this? thank you

Answer 1

`12a^4x^2 y^(10) + 6 a^(9) x^(5) y^(4) - 4 a^(3) x^(5) y^(1)`

Start by looking for the GCF for the coefficients: 12, 6 and -4
largest factor/number that divides out of all of them.
GCF for coefficients is 2

Then take the smallest exponent common to all terms for each variable.
smallest exponent for "a" is 3
smallest exponent for "x" is 2
smallest exponent for "y" is 1

GCF is: 2a³x²y
Answer A.
