What are the two consecutive positive integers if their product is 55 more than their sum?

Let’s denote two consecutive positive integers as x and x + 1.

The product of these integers can be expressed as:

Product = x * (x + 1) = x2 + x

The sum of these integers is:

Sum = x + (x + 1) = 2x + 1

According to the problem, the product of the two integers is 55 more than their sum:

x2 + x = 2x + 1 + 55

Simplifying this equation:

x2 + x = 2x + 56

x2 + x – 2x – 56 = 0

x2 – x – 56 = 0

Next, we’ll factor the quadratic equation:

We need two numbers that multiply to -56 and add to -1. The numbers that satisfy this are -8 and 7:

(x – 8)(x + 7) = 0

This gives us two possible solutions:

x – 8 = 0 → x = 8

x + 7 = 0 → x = -7

Since we are looking for positive integers, we take x = 8.

Thus, the two consecutive positive integers are:

8 and 9.

To verify:

Product = 8 * 9 = 72

Sum = 8 + 9 = 17

72 = 17 + 55

Since this holds true, our solution is confirmed.

Therefore, the two consecutive positive integers are 8 and 9.
