Question

If a and b are the zeros of the polynomial p (x) x2-5x+k such thata-b=1 find value of k

Answer 1

Answer:

Step-by-step explanation:

we know

here , A = 1 , B = -5 , C = K

sum of zeroes = -B/A

a+b = -[-5]/1.

a+b = 5................................[1]

and given , a-b = 1................................[2]

on adding

2a = 6

a = 3

b = 2

product pf zeroes = C/A

a*b = K/A

2*3= K/1

6=K

k= 6 ans
