3 0

Answer:

I think it its 0 its called the additive identity because when you add it to a number, the result you get is the same number.

Step-by-step explanation:

For example, 5 + 0 = 5 Any two numbers whose sum is zero, such as 3 and -4, because 3 + (-3) = 0.

PEMDAS
P - Parentheses (or other grouping symbols)
E - Exponents 
M - Multiplication
D - Division
A - Addition
S - Subtraction

8x[(7+4)x^2] - [(11-7)x^4]\\  \\ 8x[(11)x^2] - [(4)x^4] \\  \\ 8x[11x^2] - [4x^4] \\  \\ 88x^3 - 4x^4 \\  \\ -4x^4+88x^3

If you then want to go on to factor it, your answer would be -4x^3(x-22)
