Write the coefficient of $x^{2}$ in the following polynomials
$7 x^{3}-11 x+24$
With the help of the remainder theorem. find the remainder when the polynomial $x^{3}+7 x^{2}+17 x+25$ is divided by $x+4$
The following expressions are polynomials? Justify your answer:
$\sqrt{3} x^{2}-2 x$
The coefficient of $x$ in the expansion of $(x+3)^{3}$ is
Without finding the cubes, factorise
$(x-2 y)^{3}+(2 y-3 z)^{3}+(3 z-x)^{3}$
