Question

Write the degree of the following polynomial. $12-x+4x^3$

Answer 1

Let $p\left(x\right)=12-x+4x^3$

The degree of a polynomial is the highest power of $x$ in its expression.

Constant (non-zero) polynomials, linear polynomials, quadratics, cubics and quartics are polynomials of degree 0, 1, 2 , 3 and 4 respectively.

Highest power of $x$ in $p\left(x\right)$ is $=3$

Hence, degree of $p\left(x\right)$ is $=3$
