Question

Wat is y(y^3+2y) expanded

Answer 1

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.
