Maya is asked to find the GCF of each term in the expression 32 x y minus 18 y. Her work is shown below.
Factors of 32xy: 1, 2, 4, 8, 16, 32, x, y
Factors of 18y: 1, 2, 3, 6, 9, 18, y
GCF: (1) (2) (x) (y)
The GCF is 2 x y.
Which best describes the accuracy of Maya’s solution?
A Maya’s solution is accurate.
B Maya factored 32xy incorrectly.
C Maya factored 18y incorrectly.
D Maya factored correctly, but did not find the correct GCF.
