The product of the zeros of a quadratic polynomial $p(x) = x^{2} + 5x + 6$ is.........

Given that $x-\sqrt{5}$ is a factor of the cubic polynomial $x^{3}-3 \sqrt{5} x^{2}+13 x-3 \sqrt{5}$. Find all the zeroes of the polynomial.

If $\alpha, \beta$ and $\gamma$ are the zeros of the cubic polynomial $p(x) = x^{3} - 6x^{2} - 7x$,then $\alpha + \beta + \gamma = \ldots$

The zero of the linear polynomial $p(x) = ax + b$ is $\ldots \ldots \ldots \ldots$ $(a, b \neq 0)$.

The number of real zeros of $y = p(x)$ is $\ldots \ldots \ldots$ in the given figure.

Draw the graph of $p(x) = 3 - 2x - x^2$ and find the zeros of this polynomial.
