30y^2 - 6y

Explanation:

6y(5y - 8) + 42y

First, distribute 6y to the terms inside the parentheses, 5y and -8. To do this, multiply each term by 6y.

6y * 5y = 30y^2
6y * -8 = -48y

Re-write the equation to reflect new information:

30y^2 - 48y + 42y

Now, combine like terms. -48y and 42y are like terms, so add them together:

-48y + 42y = -6y

Therefore, your simplified expression is:

30y^2 - 6y
