Answer:

-6 and 5

Explanation:

The two numbers can be multiplied by each other to equal -30.

This means that one number is negative and one number is positive.

Since they can be multiplied to equal -30, you can ignore the negative and assuming both are positive for now.

This means that the numbers must be factors of 30.

The factors of 30 are:

1, 2, 3, 5, 6, 10, 15, 30

It must be one of these numbers.

They can be added together to get -1, where one is positive, one is negative.

Therefore, the greater number must be the negative.

Additionally, subtraction is essentially adding one number by the other negated.

This means that the numbers must be 1 away from each other.

5 and 6 are the only factors according to the above factors.

The greater number must be the negative, so the factors are 5 and -6.

Checking values:

5 * -6 = -30

5 + (-6) = -1
