It is known that the square of y = - x + 2ax-a + A + 1 has the maximum value 2 when 0 is less than or equal to X and less than or equal to 1

It is known that the square of y = - x + 2ax-a + A + 1 has the maximum value 2 when 0 is less than or equal to X and less than or equal to 1

The function is sorted into y = - (x-a) square + A + 1, and a is classified and discussed. A is greater than 1, less than o, and 0-1

If the quadratic function y is equal to the square of x minus x + A and X axis intersect at two different points, and the sum of the two points from the origin does not exceed 5?

If y = x ^ 2-x + A and X axis intersect at two different points, the corresponding equations are two x1, x2
Therefore, B ^ 2-4ac = 1-4a > 0
Yes, a
