Here we answer the question: "What two numbers multiply to -980 and add up to 56?"
The answer to your question is:
-14 and 70
Below we illustrate and prove that -14 and 70 multiply to -980 and add up to 56:
-14 × 70 = -980
-14 + 70 = 56
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 56x - 980 = 0
If so, the solution to factor the quadratic equation above is:
(x - 14 ) (x + 70)
To summarize, since -14 and 70 multiply to -980 and add up 56, you know that the following is true:
x2 + 56x - 980 = (x - 14 ) (x + 70)
