Question 1073954: What multiplies to get -0.25 and adds to get -1
Answer by jorel1380(3719) (Show Source): You can put this solution on YOUR website!
Let the two numbers be m and n. Then:
mn=-0.25 and m+n=-1
So:
m=-1-n
(-1-n)n=-0.25
-n-n�=-0.25
n�+n-0.25=0
Using the quadratic formula, we get two roots: 0.207106781187 and -1.20710678119, as m and n. ☺☺☺☺
