How to solve the univariate quadratic inequality of senior one? 1. (x-1) (the square of x-3x + 2)

(x-1) ^ 2 ≥ 0 - (why is it greater than or equal to, not greater than?)
When x = 1, it is equal to zero. When x is not equal to 1, it is greater than zero
Sure! Just give a few examples. 2 × 2 = 4 > 0, (- 2) × (- 2) = 4 > 0, (- 2) × 2 = - 4 = 0, no solution
When a > 1, the solution is x > A, X
