(9c – 8d) + (2c – 6) + (–d + 3)=

Explanation: Just addition and subtraction which is easy, I'd remove the brackets first so it won't be too confusing.

Here, just remember that:

Notice the +(-d+3), (+)(-) = - so it's -d+3

Now just addition and subtraction, for better looking and non-confusing.

9c+2c = 11c

-8d-d = -9d

-6+3 = -3

Therefore, the answer is

step-by-step explanation:

4y - 6 + 4y^2 - 9
