Solution

To determine if the expression 3x34x2x3x3x^3 - 4x - 2x^3 - x can be put in the form Ax+Bx1+Cx+1Ax + Bx^{-1} + Cx + 1, let's first simplify the expression and analyze the components.

Step 1: Combine Like Terms

Starting with the original expression:

3x34x2x3x 3x^3 - 4x - 2x^3 - x

Combine the x3x^3 terms and the xx terms:

(3x32x3)+(4xx)=x35x (3x^3 - 2x^3) + (-4x - x) = x^3 - 5x

Step 2: Analyze the Required Form

The form we want is:

Ax+Bx1+Cx+1 Ax + Bx^{-1} + Cx + 1

This includes:

  • Terms with positive powers of xx (like AxAx and CxCx),
  • A term with negative power of xx (Bx1Bx^{-1}),
  • A constant term (1).

Step 3: Identify Components

The simplified expression x35xx^3 - 5x only includes a polynomial with positive powers of xx (specifically x3x^3 and x1x^1). There are no terms like Bx1Bx^{-1} (with negative power) or a standalone constant.

Conclusion

Since the expression cannot include the required terms to match the format Ax+Bx1+Cx+1Ax + Bx^{-1} + Cx + 1 due to the absence of Bx1Bx^{-1} and the presence of the x3x^3 term, we conclude that it cannot be expressed in that form.

Final Answer

The statement is False.
