Product of two consec if even number is 125 the number

Let's solve the problem step by step.

Given:
- The product of two consecutive even numbers is 125.

Let the two consecutive even numbers be \( x \) and \( x + 2 \).

The product of these two numbers is:
\[ x(x + 2) = 125 \]

We can simplify this to:
\[ x^2 + 2x = 125 \]

Rearrange it to form a standard quadratic equation:
\[ x^2 + 2x - 125 = 0 \]

Next, we solve this quadratic equation using the quadratic formula:
\[ x = \frac{-b \pm \sqrt{b^2 - 4ac}}{2a} \]

Here, \( a = 1 \), \( b = 2 \), and \( c = -125 \). Substituting these values in, we get:
\[ x = \frac{-2 \pm \sqrt{2^2 - 4 \cdot 1 \cdot (-125)}}{2 \cdot 1} \]
\[ x = \frac{-2 \pm \sqrt{4 + 500}}{2} \]
\[ x = \frac{-2 \pm \sqrt{504}}{2} \]
\[ x = \frac{-2 \pm 2\sqrt{126}}{2} \]
\[ x = -1 \pm \sqrt{126} \]

Since \(\sqrt{126}\) is not an integer, the equation \( x^2 + 2x - 125 = 0 \) does not yield integer solutions for \( x \). Therefore, it appears there is an error in the problem statement as there are no two consecutive even integers whose product is 125.

If we assume the problem was meant to state the product of two consecutive odd integers, we can try solving for odd integers instead. Would you like to explore this?
