The product of two consecutive positive integers is 55 more than their sum. Find the integers.

Let the two consecutive positive integers be x and x + 1.

According to the problem, the product of these integers can be expressed as:

x(x + 1)

Their sum can be expressed as:

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

The problem states that the product is 55 more than their sum, so we can set up the equation:

x(x + 1) = (2x + 1) + 55

This simplifies to:

x(x + 1) = 2x + 56

Now, let’s rearrange this equation:

x^2 + x – 2x – 56 = 0

x^2 – x – 56 = 0

Next, we can factor this quadratic equation:

(x – 8)(x + 7) = 0

Setting each factor equal to zero gives:

  • x – 8 = 0 →   x = 8
  • x + 7 = 0 →   x = -7

Since we are looking for positive integers, we disregard x = -7.

Thus, the two consecutive positive integers are:

x = 8 and x + 1 = 9.

In conclusion, the two consecutive positive integers are 8 and 9.
