Answer:
2x^3 + 4x^2 - 7x + 5
Step-by-step explanation:
Start your hunt by looking for the polynomials in which the highest power of x comes first. That automatically eliminates the first two answer choices.
In which of the remaining two polynomials do the powers of x appear in descending order? Not in 6x^3+ 5x-3x^2+2. Therefore, the correct answer is the fourth: 2x^3 + 4x^2 - 7x + 5.
