Question

if a and b are the zeroes of quadratic polynomial of p(x) =x²-( k-6) x+ (2 k+1). find the value of k if a+b =ab​

Answer 1

Answer:

k = 5

Step-by-step explanation:

The sum of the roots and products of roots is equal which implies that coefficient of (-x) is equal to to the constant term.

k + 6 = 2k + 1

k = 5
