y(\(y^{3}\) + 2y) in expanded form is: \(y^{4}\) + \(2y^{2}\) .
First, distribute. / Your problem should look like: \(yy^{3}\) + y × 2y.
Second, simplify \(yy^{3}\) to \(y^{4}\) . / Your problem should look like: \(y^{4}\) + y × 2y.
Third, simplify exponent. / Your problem should look like: \(y^{4}\) + \(y^{2}\) × 2.
Fourth, regroup terms. / Your problem should look like: \(y^{4}\) + \(2y^{2}\) , which is your answer.
