11. Solving cubic equation with one variable Find the solution of MX ^ 3 + NX ^ 2 + LX + o = 0, the equation has only one real root, between 0 and 1 M. N, l, O are integers, and the sum of them is a fixed value, and the coefficients of the quadratic equation of one variable formed by their complex solutions are integers. The further relationship between the fixed value and m, N, l, O is similar to the relationship between a, B, C in the expression of Pythagorean theorem Let me change my question. A cubic equation with one variable must have a unique real root. MX ^ 3 + NX ^ 2 + LX + O has factorization (AX + b) (Cx ^ 2 + DX + e). E is an integer, and the fixed value is a prime number. There are only two prime factors. To find the formula like Pythagorean theorem, we can find the expression that m and O can be expressed by several other independent factors , cancel the real root between 0 and 1
