Question

The product of two consecutive positive integers is ${\text{306}}$, the quadratic equation to find the integers, if $x$ denotes the smaller integer is ${x^2} + x - 306 = 0$. Check whether the given statement is True or False?
$(a){\text{ }}$True
$(b){\text{ }}$False

Answer 1

Hint: Be careful while assuming the numbers, here, it is given that the numbers are consecutive, the other cases are also possible.

Consider the given equation
\[{x^2} + x - 306 = 0\]
It is given that the smaller integer is \[x\],
Therefore, the other consecutive integer can be assumed to be \[{\text{ }}x + 1\].
Since the product of the two consecutive integers is \[{\text{306}}\].
Therefore, we have,
\[x(x + 1) = 306\]
\[{x^2} + x = 306\]
\[ \Rightarrow {x^2} + x - 306 = 0\]
That is, the product of the two consecutive integers represent the quadratic equation
\[{x^2} + x - 306 = 0\]
So, the required answer is $(a){\text{ }}$True

Note: In these types of questions, the integers are first put into the respective conditions, and then solved for the required equation.
