What two numbers multiply to 638 and add up to 69?




Here we answer the question: "What two numbers multiply to 638 and add up to 69?"

The answer to your question is:

11 and 58


Below we illustrate and prove that 11 and 58 multiply to 638 and add up to 69:

11 × 58 = 638
11 + 58 = 69

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

x2 + 69x + 638 = 0

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

(x + 11 ) (x + 58)

To summarize, since 11 and 58 multiply to 638 and add up 69, you know that the following is true:

x2 + 69x + 638 = (x + 11 ) (x + 58)
