@Muffinator sorry that was an accident typing to fast
OpenStudy (anonymous):
i think i have to find the factors of 100?
OpenStudy (anonymous):
Ok, so when you factor, the middle number is how much the two add up to. The last number is how much they multiply into.

Sorry, I'm a poor explainer... lol
OpenStudy (anonymous):
lol its ok your can explain by how @uri
OpenStudy (anonymous):

OpenStudy (uri):
We have to find a number which we add or subract is =15x and when we multiply them it should be equal to 100 So -15+5=-20 and 15x5=100.
