Find the zeros of the following quadratic polynomial: $5x^2 + 8x + 3$.

If one of the zeroes of a quadratic polynomial of the form $x^{2}+ax+b$ is the negative of the other,then it

There are $x^{2}-2$ students in the class. $x^{3}-3x^{2}+5x-3$ chocolates are distributed between them. Each student should get the maximum possible number of chocolates. Find the number of chocolates received by each student and the number of chocolates left undistributed $(x \in N)$.

The product of zeros of a cubic polynomial $p(x) = ax^3 + bx^2 + cx + d$ is $\ldots \ldots \ldots$

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

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