Write the coefficients of $x^{2}$ in each of the following polynomials
$x^{3}+27$
$1$
$0$
$3$
$4$
The following expressions are polynomials? Justify your answer:
$\frac{1}{x+1}$
Factorise :
$x^{3}-6 x^{2}+11 x-6$
Expand
$(3 a-4)^{2}$
Dividing $p(x)=x^{2}+12 x+36$ by $(x+5)$ the remainder is.......
Factorise
$x^{3}+12 x^{2}+39 x+28$
