Question

Which polynomial is in standard form?

1+ 2x-8x^2+6x^3
2x^2 +6x^3-9x+ 12
6x^3+ 5x-3x^2+2
2x^3+4x2 - 7x+5

Answer 1

d

Explanation:

Answer 2

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

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.
