State whether the following statement is true or false:
The zero of the polynomial $2x + 3$ is $\frac{3}{2}$.

Factorise the following expression: $x^{3} - 125y^{3} - 15x^{2}y + 75xy^{2}$

Which of the following expressions are polynomials in one variable and which are not? State reason for your answer. If the given expression is a polynomial,state whether it is a polynomial in one variable or not: $x^{3}+y^{3}+z^{3}-3xyz$

With the help of the remainder theorem,find the remainder when the polynomial $p(x) = x^{3} + x^{2} - 26x + 24$ is divided by the divisor $x - 4$.

$4 x^{2}+11 x-3$ is a $\ldots \ldots$ polynomial.

Evaluate $66 \times 74$ without directly multiplying.
