Question

if the sum of zeroes of polynomial x2-ax+b be 5 find value of a

Answer 1

px=x2-ax+b

Here , a: 1, b: -a , c: b

We know that ,

Sum of zeroes = -b/a=a

.............................................(1)

Sum of zeroes = 5
...............................................(2)


From 1 and 2

a=5
