$25 x^{2}+9 y^{2}+64+30 x y-48 y-80 x$
$(5 x+3 y-8)(5 x+3 y-8)$
Check whether $p(x)$ is a multiple of $g(x)$ or not, where
$p(x)=x^{3}-x+1, \quad g(x)=2-3 x$
On dividing $p(x)=3 x^{3}-6 x^{2}+5 x-10$ by $(x-2),$ find the remainder.
$9 x^{2}+42 x+49$
Find the quotient and the remainder when $x^{3}+x^{2}-10 x+8$ is divided by
$x-1$
Factorise $10 x^{2}-x-24$ by splitting the middle term.
