Question

If the sum of zeroes of the quadratic polynomial 3x2 – kx + 6 is 3, then find the value of k.​

Answer 1

Answer:

Step-by-step explanation:

Hi ,

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

I hope this helps you.
