1. You need to find two numbers that's product will equal to 42 and it's sum is -1.
2. You could probably figure out it's 7 & 6 by now and now you have to figure out which one is positive or negative since they both can't be positive or negative since the product needs to be negative and if it will come out to -1. It's simple math from -7 + 6 equals -1. So the 7 would be negative in the equation and the 6 would be positive.
