$3 x - 5$

Open in App

Solution

Finding the coefficient:
A coefficient is a multiplicative factor in terms of a polynomial.
$3 x - 5$ can be expressed as $0 \cdot x^{2} + 3 x - 5$
The coefficient of $x^{2}$ in the given polynomial is zero.
Hence, the coefficients of $x^{2}$ in the given polynomials is zero.
