Answer 1

Step-by-step explanation:

⭐Question:-

if the sum of zeros of the quadratic polynomial 3 x square minus kx + 6 then find the value of k.

⭐Answer :-

Solution:-

$for \: polynomial$,

$3x {}^{2} \: - \: kx \: + 6$

$a \: = \: 3 \: ,\: b = \: - k \: , \: c = \: 6$

$now$,

$sum \: of \: zeroes \: = \: \frac{ - b}{a}$

$= > \: 3 = \: \frac{ - ( - k)}{3}$

$3 \times 3 \: = \: k$

$k \: = \: 9$
