What is the degree of $x^2 + 2x + 3$ ?

1 Answer

Jul 31, 2015

The degree of $x^2+2x+3$ is $2$

Explanation:

The degree of a polynomial is the highest degree of any of its terms.

The degree of a term is the sum of the exponents of the variables within that term.

$color(white)("XXXX")$ $x^2$ has degree $2$
$color(white)("XXXX")$ $2x = 2x^1$ has degree $1$
$color(white)("XXXX")$ $3 = 3x^0$ has degree $0$

The highest degree of the terms is $2$ and this is therefore the degree of the polynomial
