If the factors are a and b then we can create the equation as :
Here we are given the solutions as 1 and -1.
Let us plug them in the above equation and try to make an equation using it.
let a=1 and b=-1
So we have,
Simplifying,
Answer:
The equation with solutions 1 and -1 is:
If the value was initially v, then after a year it is 0.75v, after 2 years it’s 0.75²v, and so on. So after 6 years it’s 0.75⁶v.
So 0.75⁶v=7500, and v=7500/0.75⁶=$42,139.92 approximately. This is close to $42,140.
