Question

if one zero of the polynomial x2+a is -3 then find its other
zero

Ajanta Trivedi · Accepted Answer

the given polynomial is $p (x) = x^{2} + a$

if -3 is a zero of p(x).

let the other zero be x.

sum of zeroes = 0 [since coefficient of x is zero]

-3+x = 0

$\Rightarrow x = 3$

thus other zero of polynomial p(x) is 3.

hope this helps you.

cheers!!
