Question

Give a Quadratic polynomial whose roots are 1 and -1​

Answer 1

Step-by-step explanation:

Quadratic polynomial is on the form of ax^2+bx+c where a≠0

Let,

a,b are the roots

GIVEN THAT

-1,1 are the required roots of the equation

So,

(-1)+(1) = -b/a

0 = -b/a

(-1)(1) = c/a

-1 = c/a

so the quadratic equation is

x^2-1 = 0
