Question

Find the zeroes or the quadratic polynomials x2-1 and verify the relationship between the zeroes and the cofficient
​

Answer 1

Answer:

roots of the equation are 1,-1

Step-by-step explanation:

let the roots of polynomial be equal to x and y

To find zeroes of the polynomial put quadratic equal to zero

x^2-1=0

x^2=1

x=1,-1

Verifying the relationship between the zeroes and coefficient

1. alpha +Beta = -b/a

x+y=0/1

1-1=0

0=0

2. alpha×beta=c/a

x×y= -1/1

1×-1=-1

-1=-1

Hence verified
