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