若三点A[2x-1,-1],B[2,5],C[1,3]共线,则x的值为

1/4(a-b)^2x(b-a)^3x(-a-b)^5x(2a+2b)^4 5x+1=A(x-2)+B(x-1) x^2-6x+5= A(x-2)(x-3)B(x-6)(x+1) (x+a)(x+1/5)=x^2+b 求a与b的值 证明(1)|x-a|+|x-b|大于等于|a-b| (2)|x-a|-|x-b|≤|a-b| 已知：(4x+1)/(x-2)(x-5)=A/(x-5)+B/(x-2),则A= ,B=已知：(4x+1)/(x-2)(x-5)=A/(x-5)+B/(x-2),则A= ,B= 2x+b(1-x)/a 已知(5x+1)/[(x-1)(x-2)]=A/(x-1)+B/(x-2),求A-B的值 已知：4x+1/(x-2)(x-5)=A/x-5+B/x-2,求A、B的值? 已知:4x+1/(x-2)(x-5)=A/x+5+B/x-2,求A,B的值 已知4x+1/(x-2)(x-5)=A/x-5 - B/x-2,求A-B的平方根 (1)1/2x+3,3/3-2x.2x+5/4x^2-9(2)a/a-b,b/a^2-b^2,c/a+b 1、(a-b)(a+b)(a-b)²(b-a)³(a＋b)^42、(a-b)^m＋3 ×(b-a)^2 ×(a-b)^m ×(b-a)^53、(-x)^5 ×(-x^2)^5 4x+1/x^2-7x+10=A/X-2 +B/x-5 求A ,B的值 4x+1/x^2-7x+10=A/X-2 +B/x-5 求A ,B的值 因式分解（x*x+1)(x*x+1)-(4a+10b)(x*x+1)+(2a+5b)(2a+5b) 2x-3/x^2-x-A/x-1+B/x求A+B a=5x的平方+2x-1,b=-3x的平方-x+5.那么a+b=?,a-b=?,a+2b=?
