Question

in polynomial root 2x- 1 coefficient of x2

Answer 1

We know that,
$a_{n}x^n+ a_{n-1}x^{n-1}+ ........................ + a_{2}x^{2} + a_{1}x +a_{0}$ is a polynomial of n th degree , where all the powers of variables are non negative integrals .

Given polynomial,
$\sqrt{2} x - 1$

$= 0 {x}^{2} + \sqrt{2} x - 1$

There is no x² term , so it's coefficient is 0 .

Answer 2

Heya!!

Coefficients is a factor of variable in a given term.

Here x^2 has a coefficient of 0.

Hope it helps uh!
