Find the number of real zeros of the polynomial $y = p(x)$ from the given figure.

State the degree of the given polynomial: $p(x) = 5x - 2x^2 + 3$

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

Divide $3 x^{4}+5 x^{3}-7 x^{2}+2 x+2$ by $x^{2}+3 x+1$.

Divide $x^{2}+8x+12$ by $x+2$.

The graph of $\ldots \ldots \ldots \ldots$ is a curve open downwards.
