Here we answer the question: "What two numbers multiply to 438 and add up to 79?"
The answer to your question is:
6 and 73
Below we illustrate and prove that 6 and 73 multiply to 438 and add up to 79:
6 × 73 = 438
6 + 73 = 79
Are you asking because you are trying to figure out how to factor the following quadratic equation?
x2 + 79x + 438 = 0
If so, the solution to factor the quadratic equation above is:
(x + 6 ) (x + 73)
To summarize, since 6 and 73 multiply to 438 and add up 79, you know that the following is true:
x2 + 79x + 438 = (x + 6 ) (x + 73)
