A) 3x^4 + 2x^3 - 5x^2 - 7/x + 2
B) 3x^4 + 2x^3 - 5x^2 - 7/x^2 + 2
C) 3x^4 + 2x^3 - 5x^2 - 7/x- 2
D) 3x^4 + 2x^3 - 5x^2 - 7/x^3 +2

Answer 1

To simplify the given expression, first group the terms with the same exponent. Then, simplify the fraction. The equivalent expression is option A.

Step-by-step explanation:

To simplify the given expression, we need to combine like terms and simplify any fractions. First, let's group the terms that have the same exponent:

3x^4 + 2x^3 - 5x^2 - 7/x + 2

Next, let's simplify the fraction:

3x^4 + 2x^3 - 5x^2 - 7/x + 2

Therefore, the expression equivalent to 3x^4 + 2x^3 - 5x^2 - 7/x + 2 is option A) 3x^4 + 2x^3 - 5x^2 - 7/x + 2.
