What two numbers multiply to -840 and add up to -58?




Here we answer the question: "What two numbers multiply to -840 and add up to -58?"

The answer to your question is:

-70 and 12


Below we illustrate and prove that -70 and 12 multiply to -840 and add up to -58:

-70 × 12 = -840
-70 + 12 = -58

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

x2 - 58x - 840 = 0

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

(x - 70 ) (x + 12)

To summarize, since -70 and 12 multiply to -840 and add up -58, you know that the following is true:

x2 - 58x - 840 = (x - 70 ) (x + 12)
