Answer:
Here we answer the question: "What two numbers multiply to -450 and add up to 15?"
The answer to your question is:
-15 and 30
Below we illustrate and prove that -15 and 30 multiply to -450 and add up to 15:
-15 × 30 = -450
-15 + 30 = 15 Are you asking because you are trying to determine how to factor the following quadratic equation? x2 + 15x - 450 = 0 If so, the solution to factor the quadratic equation above is: (x - 15 ) (x + 30) To summarize, since -15 and 30 multiply by -450 and add up 15, you know that the following is true: x2 + 15x - 450 = (x - 15 ) (x + 30) Multiply To One Number and Add Up To Another
