Question 195244: LIST SEPARATELY, if possible, two NEGATIVE INTEGERS such that one is double the other and their product is 98.
Answer by windsolace(8)   (Show Source):
You can put this solution on YOUR website! Let the smaller unknown number be x.
Therefore the larger number is 2x
x * 2x = 2(x^2)
2(x^2) = 98
x^2 = 98/2
x^2 = 49
x = 7
Since both integers are negative, therefore the 2 integers are -7 and -14
To test:
(-7) * (-14) = 98
I used * as multiply because x is already used as a constant in the solution. Don't want you people to get mixed up. =)
