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:

-30 and -28


Below we illustrate and prove that -30 and -28 multiply to 840 and add up to -58:

-30 × -28 = 840
-30 + -28 = -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 - 30 ) (x - 28)

To summarize, since -30 and -28 multiply to 840 and add up -58, you know that the following is true:

x2 - 58x + 840 = (x - 30 ) (x - 28)
