Question

Write the degree of the following polynomial:
$x^3-{5x}^2+7$

Answer 1

The degree of a polynomial is the highest of the degrees of its monomials with non-zero coefficients.

Degree of

first term$=x^3=3$

Second term$=x^2=2$

Third term$=7x^0=1$

$\therefore$ the highest power is $3$

$\therefore$ Degree of the polynomial$=3$
