Identify Common Factor: Identify the common factor in both terms of the expression xy+y5. Both terms have a 'y' in common. In fact, y is the greatest common factor (GCF) of the two terms.
Factor Out GCF: Factor out the greatest common factor from the expression.The expression can be factored as y(x+y4).
Check Factored Expression: Check to ensure that the factored expression, when expanded, gives the original expression. y(x+y4)=y⋅x+y⋅y4=xy+y5, which is the original expression.
