Solution :
Let us assume that this number is x .
The sum of itself and its square is one and a half times their difference.
So,
( x+ x^2) = 3/2 ( x - x^2 )
We need to simplify this equation we derived to get the value of x.
> 2(x+x^2) = 3( x - x^2)
> 2x + 2x^2 = 3x - 3x^2
> 5x^2 = x
From here, x can have two values , either 5 or 0 .
These are the two possible answers .
