Question

Check whether √5 and -√5 are the zeroes of the polynomial x square minus 5.

Answer 1

Step-by-step explanation:

Given,

p(x)=x^2-5

When x=√5

So, p(√5)=(√5)^2-5=5-5=0

When x=-√5

So, p(-√5)=(-√5)^2-5=5-5=0

Therefore, √5 & -√5 are both zeroes of the polynomial (x^2-5).

Hence it is verified.
