Question

find zero of the polynomial p(x)=x2-2 state whether it is rational or irrational​

Answer 1

Given:

p(x) = x² - 2

Now,

To find zeroes of this polynomial, we have to equate it to 0.

i.e,

x² - 2 = 0

=> x² = 2

=> x = ± √2

Therefore zeroes of polynomial, p(x) = x² - 2 are,

-√2 and √2.

Since √2 cannot be expressed in p/q form where q not equals to 0.

Therefore these are irrational.

Answer 2

Step-by-step explanation:

p(x)=x²-2

x²-2=0

x=_/2

THERE FORE zeros of the polynomial p(x)=x²-2 are -_/2 , _/2

These are irrational numbers Bescause there is _/ so they are irrational
