Explanation:

Quadratic-Quadratics can be defined as a polynomial equation of a second degree, which implies that it comprises a minimum of one term that is squared. It is also called quadratic equations. The general form of the quadratic equation is: $ax² + bx + c = 0$. where x is an unknown variable and a, b, c are numerical coefficients.

Solving way-

Let the number of student=x

Number of distribution=x-1

So the formed equation is=$x(x-1)$

Given the number of chocolates is 210 so

$x(x-1)=210$

On solving the quadratic you will get 14
