If $p(x)=x^{2}-2 \sqrt{2} x+1,$ then $p(2 \sqrt{2})$ is equal to

Factorise :

$x^{2}+9 x+18$

Factorise

$144 x^{2}-289 y^{2}$

By remainder Theorem find the remainder, when $p(x)$ is divided by $g(x),$ where

$p(x)=4 x^{3}-12 x^{2}+14 x-3, g(x)=2 x-1$

Classify the following as a constant, linear,quadratic and cubic polynomials:

$y^{3}-y$

Expand

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