Question

19. If the sum of zeroes and the product of zeroes of the polynomial p(x) = x²+ (k-7)X + (k+1) are equal. find K. ​

Answer 1

Answer:

k= 3

Step-by-step explanation:

sum of zeroes = - b/a

product of zeroes = c/a

if both are equal then - b = c

therefore -(k-7)= k+1

-k +7 = k +1

2k = 6

k= 3
