Question

true or false: 2 is one zero at p(x)=x2-6+8 polynomial
​

Answer 1

Answer :-

Yes, It is a zero of given polynomial.

Explanation :-

We have to find whether 2 is a zero of polynomial :-

p(x) = x² – 6x + 8.

Put x = 2 in the given polynomial.

➞ p(x) = x² – 6x + 8.

➞ p(2) = 2² – 6(2) + 8.

➞ p(2) = 4 – 12 + 8.

➞ p(2) = -8 + 8.

➞ p(2) = 0.

Therefore, x = 2 is a zero of given polynomial.

Extra Information :-

• Polynomials are algebraic expression that consists of coefficients and variables.

• These are of 3 types :- Monomial, Binomial and Trinomial.

• These polynomials can be combined using mathematical signs like +, –, × and ÷ but is never division by a variable.
