If one zero of the quadratic polynomial $x^{2}+3x+k$ is $2$,then the value of $k$ is

Obtain the sum and the product of the zeros of the following quadratic polynomial without finding the zeros: $x^{2}-7x+10$.

The zeroes of the quadratic polynomial $x^{2}+kx+k, k \neq 0,$

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

State the degree of the following polynomial: $p(x) = 6 - 5x^3 + 4x^5 - 5x^2$.

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