Question

Q.1- solve these questions -
1. Ifp and q are the zeros of the polynomial f(x)=x²-5x+k such that p-q=1, find the value of k.
​

Answer 1

Step-by-step explanation:

sum of zeroes = -b/a

p+q= -(-5)/1= 5

i.e p+q=5..........eq(1)

p - q=1...........(2)

______________

2p =6

p= 6/2

p=3

p=3 put in eq(1)

then q= 2

product of zeroes = c/a

p×q = k

3×2=k

6=k
