What two numbers multiply to 155 and add up to 36?

Here we answer the question: "What two numbers multiply to 155 and add up to 36?"

The answer to your question is:

5 and 31

Below we illustrate and prove that 5 and 31 multiply to 155 and add up to 36:

5 × 31 = 155
5 + 31 = 36

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

x² + 36x + 155 = 0

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

(x + 5 ) (x + 31)

To summarize, since 5 and 31 multiply to 155 and add up 36, you know that the following is true:

x² + 36x + 155 = (x + 5 ) (x + 31)
