Hey frnd !!!☺

Given :
p(x)= 3 x squared -kx-4

sum of zeroes = 2

to find = k= ?

Solution :

Sum of zeroes = -b/a

2= -(-k)/3

3*2=k

k= 6

The value of k is 6

Hope this helps u ☺

Hey dear!!!

__________________________

==> In the example ,

f(x) = 3x² - kx - 4

And we have given that ,the sum of its zero is 2.

We know that ,

Sume of zeroes = - coefficient of x²/ coefficient x = - b/a

= - (-k)/3

= k/3

According to the given condition we get,

2 = k/3

k = 2*3

k = 6

Therefore, the value of k is 6 !!

Thanks !!!!
