Matey · Answer 1

You find the gcf which is 2y

you factor it out: 2y (y-2)

Robert Ramsey · Answer 2

To factor an expression, first you have to find the GCF or Greatest Common Factor of all of the pieces of the expression.

The GCF of 2y^2 and - 4y is 2y

So, to factor this expression, we need to divide all of the pieces of the expression by the GCF.

2y (y-2)

2y^2 - 4y in completely factored form is 2y (y-2)
