Write the degree of each of the following polynomials

$5 x^{2}+12 x+4$

Check whether $p(x)$ is a multiple of $g(x)$ or not :

$p(x)=2 x^{3}-11 x^{2}-4 x+5, \quad g(x)=2 x+1$

Expand

$\left(\frac{2 x}{3}+\frac{4 y}{5}\right)\left(\frac{2 x}{3}-\frac{4 y}{5}\right)$

Determine the degree of each of the following polynomials:

$-10$

Evaluate

$(555)^{2}$
