First, distribute 4y into the second binomial, then distribute 6 into the second binomial.

4y * 2y = 8y^2

4y * 5 = 20y

6 * 2y = 12y

6 * 5 = 30

Now, combine all the terms together:

8y^2 + 20y + 12y + 30

Combine like terms:

8y^2 + 32y + 30

So the fully expanded and simplified expression is 8y^2 + 32y + 30.
