Find the zero of the polynomial: $p(x) = x + 5$

Verify whether the following is a zero of the polynomial indicated against it:
$p(x) = 5x - \pi, \, x = \frac{4}{5}$

Evaluate using suitable identities: $(999)^{3}$

What are the possible expressions for the dimensions of the cuboids whose volumes are given below? $\boxed{\text{Volume} : 3x^2 - 12x}$

Expand each of the following,using suitable identities: $(-2x + 3y + 2z)^2$

Factorise: $12 x^{2}-7 x+1$
