-kx +6 is 3, then

the value of k is
answer correct and you will be marled as brainliest wrong answer will be reported​

Answer 1

Answer:

• k = -18

Explanation:

Given polynomial,

→ 3x² - kx + 6 = 0

Whose sum of zeros is 6

Find the value of k

We know that,

Sum of zeros of a quadratic polynomial:

→ coefficient of x/constant term.

→ -k/6

According to the question,

→ -k/6 = 3

→ -k = 3*6

→ -k = 18

→ k = -18

∴ The value of ‘k’ is -18

Answer 2

$\huge【\: \underline{\rm {\boxed{ \red{Answer}}}} \: 】$

Compare 3x² - kx + 6

with ax² + bx + c,

a = 3,

b = -k,

c = 6,

According to the problem given,

Sum of the zeroes = 3 ---(1)

-b/a = 3

-(-k)/3 = 3

k/3=3

k=9
