The sum of a number and it's square is one and a half times their differences. What is the number?
Assuming x^2 > x, we have
x + x^2 = 1/2 (x^2-x)
Of course, if |x| < 1, then x^2 < x, so we have
x + x^2 = 1/2 (x-x^2)
x + x^2 = 1/2 (x^2-x)
Of course, if |x| < 1, then x^2 < x, so we have
x + x^2 = 1/2 (x-x^2)
