Answer:

-5 y^2 - 3 y + 34 x

Step-by-step explanation:

Simplify the following:

2 y + 30 x - 5 y^2 + 4 x - 4 y - y

Grouping like terms, 2 y + 30 x - 5 y^2 + 4 x - 4 y - y = -5 y^2 + (2 y - 4 y - y) + (30 x + 4 x):

-5 y^2 + (2 y - 4 y - y) + (30 x + 4 x)

2 y - 4 y - y = -3 y:

-5 y^2 + -3 y + (30 x + 4 x)

30 x + 4 x = 34 x:

Answer: -5 y^2 - 3 y + 34 x
