Question

Write down the degree of following polynomials in x .

$1-x^2$

Answer 1

Finding the degree of polynomial x .

The highest power of the variable in a polynomial of one variable is called the degree of the polynomial

Here, the polynomial $1-x^2$ having two term .

The first term is constant polynomial so the degree of the constant polynomial is 0. it can be written as $1x^0$.

So the exponent of the first term $1=1x^0=0$

The exponent of the second term $x^2=2$
Since , the greatest exponent is $2$.
Hence, the degree of the polynomial is $2$.
