Question

Sum of the zeroes of the polynomial p(x)=x2-kx+ 9 is 7. Find the
value of K​

Answer 1

Answer:

K = 7

Step-by-step explanation:

Let the zeroes be a and b

Given, a+b = 7

also, a+b = k

so K = 7

Answer 2

p(x)=x2-kx+ 9 is 7

We know that sum of zeroes is -b/a

-(-k)/1=7

-- become +

k/1=7

k=7-1=6 k=6
