Here we answer the question: "What two numbers multiply to -60 and add up to -7?"
The answer to your question is:
-12 and 5
Below we illustrate and prove that -12 and 5 multiply to -60 and add up to -7:
-12 × 5 = -60
-12 + 5 = -7
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 - 7x - 60 = 0
If so, the solution to factor the quadratic equation above is:
(x - 12 ) (x + 5)
To summarize, since -12 and 5 multiply to -60 and add up -7, you know that the following is true:
x2 - 7x - 60 = (x - 12 ) (x + 5)
