Represent the following situation in the form of a quadratic equation -
The product of two consecutive positive integers is 306.

The correct answer is $x^2+x-306=0$

Let the first positive integer be x
∴ The next consecutive positive integer will be (x + 1)
Their product will be represented as x(x + 1) = x² + x = 306
⇒ x² + x = 306
⇒ x² + x - 306 = 0
