Find the number of real zeros of the following polynomial: $p(x) = 5x - 4$.

From the following figure,find the number of real zeros of $y=p(x)$:

The graph of $p(x) = x^{2} + 5x + 6$ is a..........

The zeros of the cubic polynomial $p(x) = ax^3 + bx^2 + cx + d$ where $a \neq 0$ and $a, b, c, d \in R$ are $\alpha, \beta,$ and $\gamma$. Then $\alpha \beta \gamma = \dots$

If $\alpha, \beta$ and $\gamma$ are the zeros of the cubic polynomial $p(x) = x^{3} + x^{2} - 17x + 15$,then $\alpha\beta + \beta\gamma + \gamma\alpha = \dots$

From the following figure,find the number of zeros of $y=p(x)$ :
