Question

Write the polynomial in variable x whose zero is-k÷a

Answer 1

'ax + k = 0' is the required polynomial.

Step-by-step explanation:

In the question

We have to find the polynomial in variable x whose zero is $-\frac{k}{a}$.

∴ $x = -\frac{k}{a}$

=> ax = - k

    ax + k = 0

Hence, 'ax + k = 0' is the required polynomial.

Answer 2

The polynomial in variable x whose zero is -k/a=$ax+k$

Step-by-step explanation:

Zero of the polynomial,x=-$\frac{k}{a}$

Zero of the polynomial: It is defined as the integer value of x when the value substituted in the polynomial then polynomial becomes zero.

Degree of polynomial: It depends on number of zeroes of polynomial .

Number of zeroes=Degree of polynomial

We have one zero

Therefore, degree of polynomial=1

$x=-\frac{k}{a}$

By cross multiply we get

$ax=-k$

$ax+k=0$

Using addition property of equality.

Therefore, the required polynomial is

$ax+k=0$
