Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4

Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (-2 x^3 + x^3) + (x - 3 x) + (-5 - 4):
(-2 x^3 + x^3) + (x - 3 x) + (-5 - 4)

x^3 - 2 x^3 = -x^3:
-x^3 + (x - 3 x) + (-5 - 4)

x - 3 x = -2 x:
-x^3 + -2 x + (-5 - 4)

-5 - 4 = -9:
-x^3 - 2 x + -9

Factor -1 out of -x^3 - 2 x - 9:

Answer: -(x^3 + 2 x + 9)

___________________________________________________________

Yes = (-2x^3 + x - 5)+( x^3 - 3x - 4) = ( x^3 - 3x - 4)+(-2x^3 + x - 5) = True

Proof:
 Left side

Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4

Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (-2 x^3 + x^3) + (x - 3 x) + (-5 - 4):
(-2 x^3 + x^3) + (x - 3 x) + (-5 - 4)

x^3 - 2 x^3 = -x^3:
-x^3 + (x - 3 x) + (-5 - 4)

x - 3 x = -2 x:
-x^3 + -2 x + (-5 - 4)

-5 - 4 = -9:
-x^3 - 2 x + -9

___________________________________________________________
Right Side.

Simplify the following:
x^3 - 2 x^3 + x - 3 x - 5 - 4

Grouping like terms, x^3 - 2 x^3 + x - 3 x - 5 - 4 = (x^3 - 2 x^3) + (-3 x + x) + (-4 - 5):
(x^3 - 2 x^3) + (-3 x + x) + (-4 - 5)

x^3 - 2 x^3 = -x^3:
-x^3 + (-3 x + x) + (-4 - 5)

x - 3 x = -2 x:
-x^3 + -2 x + (-4 - 5)

-4 - 5 = -9:
-x^3 - 2 x + -9

Factor -1 out of -x^3 - 2 x - 9:
Answer:  -(x^3 + 2 x + 9)
