If X. (power 0 of x) is the root of the quadratic equation AX & sup2; + BX + C = 0 (a ≠ 0), a = B & sup2; - 4ac, B = (2aX. + b) & sup2;. Try to compare the size of a and B

If X. (power 0 of x) is the root of the quadratic equation AX & sup2; + BX + C = 0 (a ≠ 0), a = B & sup2; - 4ac, B = (2aX. + b) & sup2;. Try to compare the size of a and B

The zero power of any number is 1, so X. is 1, so it's easy to solve. A is 0, because X. (the zero power of x) is the univariate quadratic equation AX & sup2; + BX + C = 0 (a ≠ 0). The root is a root, which can be said to be two identical roots. First of all, a is not equal to 0, so B is greater than or equal to a,
Hope can help you, a lot of advice!
