Question

Find the value of k if the polynomial 2x^2 - 3kx+5 has 9 as the sum of zero

Answer 1

Hiii. .....friend

The answer is here,

$= > \: 2 {x}^{2} - 3kx + 5$

Sum of the zeroes => -b/a.

=> 9 = -(-3k)/2

=> 9 =3k/2.

=> 18= 3k.

=> k=18/3.

=> K= 6.

:-(Hope it helps u.

Answer 2

Concept Introduction:

A mathematical expression which is derived by two expression connected by a equal to (=) sign, is known as equation. All scientific calculations and fractions are made of many mathematical equation.

Given:

We have been given a equation, 2x^2 - 3kx+5.

To Find:

We have to find the value of k.

Solution:

According to the problem,

Sum of the zeroes => -b/a.

=> 9 = -(-3k)/2

=> 9 =3k/2.

=> 18= 3k.

=> k=18/3.

=> K= 6.

Final Answer:

The value of k is 6.
