Here we answer the question: "What two numbers multiply to -630 and add up to 53?"
The answer to your question is:
-10 and 63
Below we illustrate and prove that -10 and 63 multiply to -630 and add up to 53:
-10 × 63 = -630
-10 + 63 = 53
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 53x - 630 = 0
If so, the solution to factor the quadratic equation above is:
(x - 10 ) (x + 63)
To summarize, since -10 and 63 multiply to -630 and add up 53, you know that the following is true:
x2 + 53x - 630 = (x - 10 ) (x + 63)
