Question

What are two numbers that when multiplied equal -30 and when added together equal 1?

Answer 1

The answer is 6 and -5

Answer 2

5 and 6

Explanation:

-5 x 6 = -30

-5 + (6) = 1

x2 + 1x - 30 = 0

(X - 5 ) (X + 6)

To summarize, since -5 and 6 multiply to -30 and add up 1, you know that the following is true:

x2 + 1x - 30 = (X - 5 ) (X + 6)
