Theo factored a greatest common factor (GCF) of 3x^2y
from the expression 15x^3y^2-6x^4y^3+9x^2y2.
What error did Theo make, if any?
Theo could have factored a higher coefficient from the expression.
Theo could have factored an additional y variable from the expression.
Theo didn't make an error. He factored the correct GCF.
Theo could have factored an additional x variable from the expression.
