Question

find the zeros of each of the following quadratic polynomial and verify the relationship between the zeroes and the Cowfcients 1) f (x) = x2 - 2x - 8​

Answer 1

Step-by-step explanation:

hope this answer helps you

Answer 2

Answer:

Step-by-step explanation:

f(x)=0

⇒x²-2x-8=0

⇒x²-4x+2x-8=0

⇒x(x-4)+2(x-4)=0

⇒(x-4)(x+2)=0

⇒x=4 or -2

let be α=4 and β=-2,

now α+β=2=2/1=-(coefficient of x)/coefficient of x²

αβ=-8=-8/1=constant term/coefficient of x².
