Here we answer the question: "What two numbers multiply to -426 and add up to 65?"
The answer to your question is:
-6 and 71
Below we illustrate and prove that -6 and 71 multiply to -426 and add up to 65:
-6 × 71 = -426
-6 + 71 = 65
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 65x - 426 = 0
If so, the solution to factor the quadratic equation above is:
(x - 6 ) (x + 71)
To summarize, since -6 and 71 multiply to -426 and add up 65, you know that the following is true:
x2 + 65x - 426 = (x - 6 ) (x + 71)
