Question

if two zeroes of polynomial are 2, - 7 find quadratic polynomial

Answer 1

Answer:

let alpha be 2 and beta be- 7

Step-by-step explanation:

so,

aplha+beta=b/a (according to formula)

so- 7+2=b/a

-5=b/A

now ,alpha×beta =c/a (according to formula)-

so 2×-7=c/a

=-14

so we get a=Xsquare

b=-5x

c=-14

so,according to the formula we get,

="Xsquare - 5x -14"
