What two numbers multiply to 105 and add up to 106?

Here we answer the question: "What two numbers multiply to 105 and add up to 106?"

The answer to your question is:

1 and 105

Below we illustrate and prove that 1 and 105 multiply to 105 and add up to 106:

1 × 105 = 105
1 + 105 = 106

Are you asking because you are trying to figure out how to factor the following quadratic equation?

x² + 106x + 105 = 0

If so, the solution to factor the quadratic equation above is:

(x + 1 ) (x + 105)

To summarize, since 1 and 105 multiply to 105 and add up 106, you know that the following is true:

x² + 106x + 105 = (x + 1 ) (x + 105)
