what are factors of -20 that add to be one
LOL - I did your earlier problem
5 and -4
when you have a question like that, write out the prime factors of 20 for example
20 * 1
10 * 2 --> 5 * 2 * 2
well 5*2*2 looks like 5*4
To find the factors of -20 that add up to be one, we first need to determine the possible factors of -20.
The factors of -20 are pairs of numbers that multiply together to give -20. Since -20 is a negative number, one of the factors must be positive and the other must be negative.
Here are the pairs of factors that multiply to give -20:
1. (1, -20)
2. (-1, 20)
3. (2, -10)
4. (-2, 10)
5. (4, -5)
6. (-4, 5)
Now we need to find the pair of factors whose sum is one.
Checking the above pairs, we can see that (-4) + 5 equals one. Therefore, the factors of -20 that add up to be one are -4 and 5.
