What two numbers multiply to 155 and add up to 156?

Here we answer the question: "What two numbers multiply to 155 and add up to 156?"

The answer to your question is:

1 and 155

Below we illustrate and prove that 1 and 155 multiply to 155 and add up to 156:

1 × 155 = 155
1 + 155 = 156

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

x² + 156x + 155 = 0

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

(x + 1 ) (x + 155)

To summarize, since 1 and 155 multiply to 155 and add up 156, you know that the following is true:

x² + 156x + 155 = (x + 1 ) (x + 155)
