I'm very glad to answer your questions. Skyhunter 002 will answer your questions
If you don't understand this question, you can ask,

Determine the sign of the product term a13a24a31a45a52 of the fifth order determinant?

The reverse order number of column label permutation t (34152) = 2 + 2 + 0 + 1 = 5
So this is a minus sign

Factorization factor X & # 178; &; Y & # 178; &; 4x + 4Y = 0

(x+y)(x-y)-4(x-y)=0
(x-y)(x+y-4)=0
So X-Y = 0 or x + y-4 = 0

If point a (1,3), B (5, - 2) and point P make | AP | - | BP | maximum on the x-axis, then the coordinates of P are______ ．

The symmetric points of point B about X axis are C, C (5, 2), so the equation of line AC is Y-3 = - 14 (x-1), that is, 4Y + X-13 = 0. Let y = 0, then x = 13, so p (13, 0). So the answer is: (13, 0)

Given the function y = f (2x-1) = 4x & sup2; - 5x + 1, the domain of definition is [- 1,2], find the function y = f (x)

Method 1: the matching method f (2x-1) = 4x & sup2; - 5x + 1 = (4x & sup2; - 4x + 1) - (1 / 2) (2x-1) + (3 / 2), = (2x-1) & sup2; - (1 / 2) (2x-1) + (3 / 2), ｜ f (x) = x & sup2; - (x / 2) + (3 / 2), and in F (2x-1), - 1 ≤ x ≤ 2, - 2 ≤ 2x ≤ 4, - 3 ≤ 2x-1 ≤ 1, the analytic expression of the function f (x) is f (x) = X

Given that the image of a quadratic function passes through points a (2,4), B (- 1,0) and the length of the line cut on the x-axis is 2, the analytic expression of the quadratic function is obtained
The more detailed, the better. I don't understand this very well

Let the quadratic function y = ax & # 178; + BX + C intersect with the X axis as x1, X2 (x2 > x1) x2-x1 = √ [(x1 + x2) &# 178; - 4x1x2] = √ [(B & # 178; - 4ac) / A & # 178;] = 2B & # 178; - 4ac = 4A & # 178; 1) substitute a (2,4), B (- 1,0) to get: {4 = 4A + 2B + C2) {0 = A-B + C3) simultaneous 1), 2), 3) to get: a = 4 / 15, B =
