Question

Write the polynomial in Index form. 3x2 + 5x3 – 7​

Answer 1

Answer:

The coefficient form of the polynomial is (5,0,0,0,−1)

Therefore, the index form of the polynomial is 5x

4

+0x

3

+0x

2

+0x−1 or 5x

4

−1

Answer 2

❥ Given Data : Polynomial P(x) = 3x² - 5x³ + 7

❥ To Find : Degree of the Polynomial

❥ Answer : 3 is the Degree of Given Polynomial

$\rule{315}{3}$

❥ What is Degree of Polynomial ?

Degree of Polynomial is known as The Highest Exponent or Degree in the Polynomial (Example : 2x² + 1 - x has 2 as the Highest Exponent, Hence 2 is the Degree of 2x² + 1 - x )

❥ Step by Step Solution :

In the Polynomial P(x) = 3x² - 5x³ + 7, the highest exponent is 3 of variable x. Hence 3 is the Degree of Polynomial 3x² - 5x³ + 7

$\rule{315}{3}$
