Question

2 multiple choice 1 point put the polynomial in standard form: $5x - 3x^2 + 7x^4 + x^3 - 2$ $5x^4 + 5x - 2$ $7x^4 + x^3 - 3x^2 + 5x - 2$ $-2 + 5x - 3x^2 + x^3 + 7x^4$ $7x^4 - 3x^2 + 5x + x^3 - 2$

Explanation:

Step1: Recall standard polynomial form

Standard form of a polynomial arranges terms in descending order of the exponent of the variable.

Step2: Identify term exponents

The terms and their exponents:

• $7x^4$ (exponent 4)
• $x^3$ (exponent 3)
• $-3x^2$ (exponent 2)
• $5x$ (exponent 1)
• $-2$ (exponent 0)

Step3: Arrange terms descendingly

Order terms from highest to lowest exponent:
$7x^4 + x^3 - 3x^2 + 5x - 2$

Answer:

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