Question

If the sum of zeroes of quadratic polynomial 3x^2+kx-5 is 4 then find the value of K​

Answer 1

Answer:

so a+b = 4

Step-by-step explanation:

as coefficient of x^2 = 3

sum of zeroes must be = - k/3                   (- coefficient of x/coefficient of x^2)

but sum of zeroes is 4

so k/3 = 4

k = 12                                      (multiplying 3 on both sides)
