-14 and -14 Add them together to get -28 Multiply them to get 196
The factors of 21 are 1, 3, 7 and 21. No two of them add up to 21.
1/2 or .5
If you add them together it does equal two but it can also equal a window.
If you have -1 and multiply it negitivly by 1, it's like taking it back one one a number line. Two negatives multiplyed equals a positive.
1 multiplyed by 1 is 1!

The factors of 21 are 1, 3, 7 and 21. No two of them add up to 21.
When the "factors" of a number are listed, the list is usually restricted to positive factors. Then there would be no answer to the question, because no group of positive numbers can add up to make zero.
1/2 or .5
17 x 17
If you add them together it does equal two but it can also equal a window.
There is no answer to this. The factors of 15 are 1, 3, 5 and 15. The only numbers that add up to four are 1+3, 4+0 and 2+2.
1 x 289 = 289
If you have -1 and multiply it negitivly by 1, it's like taking it back one one a number line. Two negatives multiplyed equals a positive.
the two factors that equal are 155 *2 by ivelisse cruz in 6th grade 2012
