As per the given figure,the graph of $y=p(x)$ has $\ldots \ldots$ real zeros.

Are the following statements 'True' or 'False'? Justify your answers.
If all three zeroes of a cubic polynomial $x^{3}+ax^{2}-bx+c$ are positive,then at least one of $a, b$ and $c$ is non-negative.

Identify the type of the following polynomial based on its degree: $p(x) = (x - 15)(x + 15)$

One of the factors of $p(x) = x^{3} + 2x^{2} + 3x + 2$ is:

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

If the zero of the polynomial $p(x) = 3x^{3} - x^{2} - ax - 45$ is $3$,then $a = \dots$
