Answer:
Solution is 1 (one).
Step-by-step explanation:
- The equation
can be solved by solving first the expression in the numerator. This is done by solving
.
- Then, you just have
. The negative is canceled when it appears twice, so we just have to solve
(any number divided by itself equals to one).
Let the two factors be x and y.
Two factors that multiply to -1:
Two factors that add to 1:
From the second equation:
Plug x back into the first equation:
There are no binomial pairs that result in this quadratic. Thus we must use the quadratic formula.
x = -y =
Either x or y could be the positive factor. The other variable would have to be the negative factor.
Just a sidenote: is actually called the "Golden Ratio" because the ratio is found so often in beautiful example in nature.
