Marcia claims that the GCF for (2x2 + 4xy + 8xy4) is 8x2y4.

Explain if she correct or not. If she is correct, justify her claim. If she is not correct, explain her error and state the correct GCF.

Respuesta :

she is incorrect 

the GCF of 2, 4 and 8 is 2  (not 8 has she has written)

the GCF of x2, xy and xy4  is x   not x2y4

Correct GCF of the 3 terms is 2x
