(K-3) x ^ (K-2) + x ^ 2 + KX + 1 = 0 is a quadratic equation of one variable about X, then the value of K is Note that it's a quadratic equation of one variable, I think it's 2.3.4, But the teacher said 2 is wrong, thank you very much On the first floor, when you say k = 2, the original formula should be - 1 + x ^ 2 + 2x + 1 = o x ^ 2 + 2x = 0 If the equation has no solution, can't it be a quadratic equation with one variable When x = 2, can (K-3) x ^ (K-2) be regarded as no or - 1

2 should be right. The first item of 2 is - 1
As for the upstairs said that there is no solution, there is no need to consider the problem
