Question

Why x+3 is linear polynomial​

Answer 1

Explanation:-

x+3 is a polynomial with degree 1. Degree is the highest power of a term in a  polynomial. Here, in x+3, the highest power is 1 ( $x^{1}$).

Therefore x+3 is a linear polynomial.

Answer 2

As per the data given in the question,

We need to explain the reason behind that why $(x+3)$ is termed as linear polynomials.

For explaining the reason that the given number/ expression is linear polynomials let us first understand that what actually is linear polynomials.

As we know that,

Linear Polynomials are those polynomial in which the degree of the polynomials is equal to one, i.e., the power of highest exponent of the variable present in the expression is one.

The general form of linear polynomials is $P (x) = ax + b$ , where a and b are any constant.

So, now observing the expression given in the question,

$(x+3)$, here the maximum power of the variable which is present in the expression is 1.

So, the given variable will be considered under the category of linear polynomials.
