Question

Give an example of a polynomial, which is Trinomial of degree $2$

Answer 1

Example for the required polynomial :

1. Terms are the values on which mathematical operations take place in an expression. A term can be a constant or a variable or both. For example, in the expression $3x+8$; $3x$ and $8$ are terms. i.e. there are two terms in this expression.
2. Trinomial is a polynomial which has only three terms.
3. Degree of a polynomial is the highest power of variable in a polynomial equation.
4. Now, a trinomial of degree $2$ is a polynomial which consists of only three terms with highest degree $2$

Hence, $x^2+2x+5$ is an example of a trinomial with highest degree $2$
