What two numbers multiply to 400 and add up to -58?




Here we answer the question: "What two numbers multiply to 400 and add up to -58?"

The answer to your question is:

-50 and -8


Below we illustrate and prove that -50 and -8 multiply to 400 and add up to -58:

-50 × -8 = 400
-50 + -8 = -58

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

x2 - 58x + 400 = 0

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

(x - 50 ) (x - 8)

To summarize, since -50 and -8 multiply to 400 and add up -58, you know that the following is true:

x2 - 58x + 400 = (x - 50 ) (x - 8)
