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

Open in App

Solution

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 $= 7 x^{0} = 1$
$∴$ the highest power is $3$
$∴$ Degree of the polynomial $= 3$
