Given that a, B and C are odd numbers, it is proved that the root of the equation AX square + BX + C = 0 must be irrational

If x is a rational number,
Then x & sup2; must be rational,
If X & sup2; is odd, then ax & sup2; must be odd and BX must be odd,
Then ax & sup2; + BX must be an even number, and C is an odd number, ‖ ax & sup2; + BX + C ≠ 0
If X & sup2; is even, then ax & sup2; must be even and BX must be even,
Then ax & sup2; + BX must be an even number, and C is an odd number, ‖ ax & sup2; + BX + C ≠ 0
X is not a rational number, X is an irrational number;
The root of the equation AX & sup2; + BX + C = 0 must be irrational
