NCERT Exercise Exercise 4.1

Represent the following situations in the form of quadratic equations.

(ii) The product of two consecutive positive integers is 306. We need to find the integers.

Let the first integer number = x
Next consecutive positive integer will = x + 1
Product of both integers = x × (x +1) = 306
⇒ xx = 306
⇒ xx - 306 = 0
