Q3 of 90 Page 27

Verify whether the values indicated against the following polynomials are zeroes of the polynomial.

p(x)=4x+5; x= -5/4

After substituting the value for variable in the polynomial if we get 0 then that value is called zero of the polynomial.


It means that if p(x) = 0, then x will be called as the zero of the polynomial.


p(x) = 4x + 5; x = -5/4


substituting in 4x + 5


⇒ p() = 4 + 5


⇒ p() = -5 + 5


⇒ p() = 0


Yes is zero of polynomial p(x) = 4x + 5
