Answer:
2x^2(x^3+3x+8)
Step-by-step explanation:
Factor out the gcf which in this case is -2x^2 because that's the greatest factor all of the terms have in common this results in -2x^2(x^3+3x+8)
Btw the ^ represents the exponent
56/125-177/625= 280/625 - 177/625 = ( 280 - 177 ) / 625 = 103 / 625 = 0.1648
Short Answer: Combine like terms
Remark
Just from what I see here, remove the brackets first and combine like terms second.
Discussion
8 - 2x + 4 The like therms are 8 and 4 First step
12 - 2x That's the answer. Don't go any further. 2nd and last step
