What two numbers multiply to -290 and add up to 143?

Here we answer the question: "What two numbers multiply to -290 and add up to 143?"

The answer to your question is:

-2 and 145

Below we illustrate and prove that -2 and 145 multiply to -290 and add up to 143:

-2 × 145 = -290
-2 + 145 = 143

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

x² + 143x - 290 = 0

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

(x - 2 ) (x + 145)

To summarize, since -2 and 145 multiply to -290 and add up 143, you know that the following is true:

x² + 143x - 290 = (x - 2 ) (x + 145)
