Question

Find the zero of the polynomial p ( x ) = 5x + 1 .​

Answer 1

Answer:

The zero of the polynomial is -1 /5

Step-by-step explanation:

ATQ ,

p ( X ) = 5x + 1

To find the zero of a polynomial , equate the given polynomial to 0 and find X

so, p ( X ) = 0

5x + 1 = 0

5x = 0 - 1

5x = -1

X = -1 / 5

Therefore the zero of the polynomial is -1 / 5

Answer 2

The zero of the polynomial p ( x ) = 5x + 1 is -$\frac{1}{5}$.

Given:

The polynomial p( x ) = 5x + 1.

To find:

The zero of the polynomial needs to be determined.

Solution:

To find the zero of the polynomial p( x ) = 5x + 1 putting its value equal to zero.

⇒  p( x ) = 0

⇒ 5x + 1 = 0

⇒ 5x = -1

⇒ x = -$\frac{1}{5}$

Hence, the value of the zero of the polynomial is -$\frac{1}{5}$.

For verifying that the value of zero of the polynomial is x = -$\frac{1}{5}$ put this value of x in the polynomial if it is equal to zero then it is zero of the polynomial and if it is not equal to zero then it is not zero of the polynomial.

⇒ 5x+1 = 5$\times$$\frac{-1}{5}$ + 1 = -1+1 = 0.

Hence, verified that x = -$\frac{1}{5}$ is the zero of the polynomial.
