Question

3√5 is a zero of a polynomial p (x).
Find the value of 3p(3√5)+23

Answer 1

The given question is 3√5 is a zero of a polynomial p (x).

we have to find the value of 3p(3√5) +23

A polynomial is an expression composed of variables, constants and exponents that are combined using mathematical operations like addition, subtraction, multiplication and division.

The major rules of polynomial is an algebraic expression should not consists of square root of variables.

If 3√5 is the zero of the polynomial.

then p(x) =0.

where x=3√5.

p(3√5) =0.

Then we have to find the value of 3p(3√5) +23

3 times of p(x) =3p(3√5) +23.

Therefore, the result is 3(0) +23=23.

Hence, the value of 3p(3√5) +23=23.
